So this work charity car was what we did in the last. Six or seven years applying microfluidics to your neighbor genomic profiling and I will talk about why that is about so the idea of procedure Madison certainly is that you are want to gather smarter so you can do more like information about the patient and that they use that information to hopefully Tater to pass a treatment of other particular patients and the Certainly this type of information in the post the genome Ira you always you know genomics and also IP genomics transport Your makes proteomics So one thing I want to remind you is that the genomics is fairly constant. What that means is you are in say a treatment period say half a year a Y. year for a cancer patient the genomics pretty much stayed stable course and the second the wall it's also notational specific city meaning if in the past the genomics. Or they look at the same results and the art of how a poll makes talking about here every genomics transport you're makes They are a fairly dynamic can also teach your specific. Opportunities for a tool monitor or. Because of that they will be specific and also they are fairly trends in and that they and I make they are into these they are low and so hopefully by following these kind the different layers of regulate hurry systems that allows you to follow the easy self. And. A little bit about that hey say is certainly you know people realize D.N.A. sequence is very important in terms of the. However people also realize from earlier point about the that the sequence. That they could hates the that they rattle point or the biology because if you look at to the process. You know when the human being you know from a fertilized diagnose reaches the circle in a single cell and the keeper of the officiating into the wiring to a janitor human body which includes allowed. In the tissue of hives drastic a day for morphology for the South Wales and also drastic more like about their front to what I can about allergy so that means. That they should have the same genomics and that means something else is playing important role in such there. And the art of process you can see there is things like mammary or learning or of the action for example you listen to my power crane now hopefully sour days later some of the ask you all this talk is about he considered how something that means this experience leaves a biochemical marking or mind that obviously this kind of change cannot be a genomics mutation so it has to be something that's more trends into more faster than that so that people recognize that. Involve the bad hypo process too and if you look hard to the. DRUG. This is actually NY entirely surprising because if you look in. Your house twenty three pairs away and it's not just the wary long run the D.N.A. It's double stranded D.N.A. wrapped around a protein called a peaceful and if you allow any changes to the peaceful For example if there were a group through the tail or a seed through the tale that's how facts are. Accessibility of the song that's how facts that come from a show the chromosomal big factor was a change. In the local area and so he's got modifications of one type. That changes the transcription. Expression and the hype but that doesn't change the D.N.A. sequence OK the art of hybrids call the PM methylation that he feels. To the side of the scene this is one of the four bases for nuclear Hi it's the Ohio in the you know the uni then that I can change is the charge changes the conformation changes the accessibility so changes are all call of the. Changes and they are even while the enormity of. The seas they are local and you know it's very wide ranging in terms of the scene moment so why important message like I'm Irish in the in the earlier slides is that the I.P.T. Normally it's wire marched a shoe in the south specific that means they feel I'm alive is the established IP genome. Using say model sounds that that would be there for and from using. A cell from the bones or Otter. So the current higher for it is that people are establishing the reference IP genomes for different hafe you would have us there for us for humans certainly and also for the U.C. important model animal like mice and certainly the goal is that. You might want to apply this to the clinical. Clinical. World or the way it would appear it's obviously on there for us they establish the reference IP genomes what that means is water. I mean if. There was. A feature a low clock and after that you sort of want to establish what he looks like one that they tease or curse and of a your comparative tool hopefully the so-called a function I know teach and the IP genome meaning a certain area are certain feature is connected with sort of phenotypes or certain you know date OK then you can now you can profile a patient using that patients much cereal you're saying now reach category I can put this by they get a page in the into you know that's a sort of call the patient the stratification you say OK there to be you know that the patient to this category therefore they stop or treat them and it would be so that historically say by seventy percent a fact to this particular patient that's holy or really. Pay well over this kind of tailored treatment of a particular patient or using that such information certainly if you understand that you know more and how their changes with of these seas that gives you a biomarkers that gives your targets potentially to work for the for the The Art of a way feel me out and so certainly a problem with me how process is the order to work with piece of the materials you're limited by the amount how cells of readable you you know so I allays there are some examples you know how fine needle biopsy you know several hundred thousand cells see you know tens of thousands of cells and you know and a day. Mainly in those cells if you had to resign action that you were more or the post-mortem human some poll number in some poll so are mainly in the. I and but. If you try to look at the circulating tumor cells you really only got to one to attend such cells from one million million later then you're really roughly ten to one hundred of them full. On to sort of a you know addition to that again genome is specific to the south type you're probably we'll do some sour isolation to generate a homogeneous population those cells before passing that to the pontiff order the Krays of the number of cells of we're able to we'll. Find only I think a large number of marks means to be prostate so each individual marker with the require a separate c So I was a little bit more about that about so why I say we first is called a personal piece and this is I will save for a examining. You know why the peaceful modification so this is a gold standard and I would say the way it works is that you're first the how cells you break the cells to extract. And then because you want to be compatible with them that's generation sequencing now we need to operate across all me into smaller pieces anywhere from two hundred to six hundred B.P. for you to piece and then now you're going to include. These pieces that come pain contain the. More they find at least on your targeting that for example you interesting in H. story K. for I me three that would be the H. story. With slicing for prying the by. Then they are high on the body targeting that and they are how these magnetic obese code here there is such antibody then they would have pulled down the fragments containing. Such a fight he stole and the day you can test the leaving just the. Interacting with the still and then you can do either Q. P.C.R. if you mind that you want to see if this particular gene is interacting with the store or you can try to do sequencing which gives you that you know why the profile of all the locations in the genome has this small they fight he's still OK So the problem with Why are powerful as see the problem is that I see is that they require a million cells and like Quad for you just imagine that you know earliest allies you don't normally have them on the it sells to go out and certainly a lot of the procedure with the manual so that it requires multiple days for such a C. and. For his the modification certainly or how different the modification the figure here shows that they're out there for a face on tails and I had different location there for an amino acid is. There for the modifications so so there are. A base for it to explore relate to. The state still cold or so-called. So they're obviously how being they will open the Order years to. Decrease the import of the sound number required of us such as a I think of the that who that's how you rather that's what we need they wound up the I think that there are roughly. That are using chameleon cells we were able to work with less than one hundred cells and there was a good drops chip with a well. That can work with a single cell the problem is that. There wasn't a whole lot of information generated on single cell they How about one. As a result of sell so I'll do a comparison you know about someone with when we talk about that they you know so before we pericope this problem one thing without a mirror is obviously going to be the minimal number of cells in your to require for such a chip see say maybe there is a theoretical number because idea about so one thing we can see there is that you look at these labor per precinct here they need to prepare a library for sequencing normally requires about twenty people anywhere from ten to twenty people where I'm. OK they are either you look at the. Data OK that they've had their way or read that is the X. axis is the location in the genome the way Access is the signal after the chip seek process if we'll see a peak here that means that a particular location you know how that particular modify the peaceful at that location so this is her genomes profile they were roughly look. At all these peaks that Gadar What's the fraction of the genome occupies OK we look at that it's roughly around five percent OK So if you're considered out there then for Chip seek I would say I describe your roughly supposed to collect. The code whole. Fragments if you need to generate a twenty Pico gram of D.N.A. and that each cell contains of all six people Gram the simple calculation shows if you're collecting them one hundred per cent you only need to sixty seven cells for such work so that's what we were shooting for once we haue idea about that so what we demonstrated in this call most chip see Michael floating all. Three Washington feet is that we were able to collect it being a battered and. To order magnitude of the Compared to this NATO are to add a point and that allowed us to look at really you'll just one hundred cells to generate such data and process takes only about less than two hours so that her going to call you Mabel or here is where a simple as I will show you look at that you made here just a how a single chambre here microfluidic chambre and then we form a pack the bad so we are chemical engineers we like pack the baddest so and then you know how a single wall here that enable us to collect that the immense wire of the crummy thing fragments I shall say with wire high efficiency then we haue a war game to remove the now specific odds option so the process works like this so you know how big a fairly big chamber and of the wall here can be close the how fully meaning that the particle will be stopped but the the the wall heard of fluid the kind of see through such as a drought or so while you do that and you compact the microscope bees I guess such as to dry out here and there your family is packed the bad and the once you have that so you can follow the crawl meeting fragments through such a structure and then now they need to squeeze through the the winding past ways between the particles and the date there are where a small gaps between the particles Now you know this is like a C.V. in structure now however high captions in the efficiency by the way the beads are cold here the way is on table they targeting the particular type of peaceful in these fragments OK but certainly the trance is my improved specific your target you also seem prone increases nonspecific as option so you have to how long. The war to go is that and then so what we did was just the make an equally a move to be back on the force in the Chambre by applying pressure pulses either through hands of the Chambre So why are you leave him. Turned out to be working OK and that then after the war signori more than our for the safeguards option you can do without her a couple of homes and then yeah and then you can you know the washing of the beads you can collect the bees are for the of the micro fertility of the Weiss they occur. Sort of that as the song and the piece of the D.N.A. prepared elaborate just like our body else and that then we come prepare a labyrinth for a sequencing and. Here I'm sure a video that shows the movement of the war scene of the piece so you can see the bees are moving back in the force in the channel like crazy so so there's mechanical washing and then we can sort of. Before we do sequencing it's a low cost way to look at it if it works or not so the way we look at it is we look at the Richmond meaning we know certain locations that's supposed to how this signal. Is the modification I have that particular gene and that then there is our area that you know the signal of to be very low and that now you want to see the maximum or differentiation between the two types of pause if you will recall and. Then you can hear my is the combination in terms of war amount of bees and their fingernails and you can see sort of the other sort of conditions that the contrast is bad her you know that So these are cool combinations and so basically our results show that we can pretty much collaring you know us march of being we want but if we look at the reach went. You know one day you reach middle school that we can fill collect anywhere from five to eight per cent of the crummy eighteen you know just the water we asked them a table to became is and that's all we feel we are pretty much collecting a tad to the theoretical level certainly there is no guarantee that we are only collecting that would be in or call the core meeting fragments there but we are we are you by neighborhood now or the last so this is the data again the X.X. says is the location of the genome if you're seeing a peek at that's in the case that particular location or how this type of he's the most vacation we look at the would have is a useful modification why it's an active weeping markets for a. Me three he already is the sort who indicates Warda. Story is. Twenty seven A C. so we work our way down using pencils and cells per hour as say and all the way down to one hundred cells pricey so you can see we did the how higher noise level while you know how life cells but now were less for the for the major peaks we are seeing the same thing in the same information OK I guess history Kate when they say when they see work sell a better you know you terms of seen exactly that then tickling information there. Now this is now we can work with one hundred cells we can work with tens of cells so that's the thing we are thinking about his like I'm Irish in the bureau of marks you know on the low cat then you know if you really want to push this for personal Madison you're probably how large number zero patients I'm holds to love cats different types and so on so you want to work with high throughput meaning you're on their conduct of the sizes multiple wives in the same routine it's really so the way why we wanted to with theory is that we can operate for the motive of the WEISS You know isolate him to fashion the they are not to communicating with the charger but he just of Samael Taney Asli So here see. OK so what you can see is that. You know we can you know this is so the Washington guys that's more pronounced you can see they are moving target or sort of the same way or fashion then we are operating for I see as they move in the US away if. We can easily make a bigger number or really it's working together you can see the walls are for lashing and you know you sort of remove the some holes the chips the same routine the Asli tool so that's possible you know another piece of work we saw how you can also start with the same sample but this blade that four way is the you know so that is a labor tree key in the sense that they feel steel how packed the bad you know how a lot of pressure drop I think US chemical engineer we can easily appreciate that and so we change that how about that to how well for the guy is the bad meaning that the you know how a flow then you know how a magnet into the pool to be so counterbalance of the. Two forces and that they are how the bees basis of spawn they are the in the solution so that's less than say the last pressure drop it works maybe a same or a very and and we can. Make them work. You know and war in art of things art of stamps OK yeah to make it even simpler what we thought is also that. Says We are working with the goal is to work with a small number of cells and they are not generating a whole lot of Crimea here for humans they are probably don't need a whole lot of surface area for such as often so we were thinking if we haue a bigger channel maybe the substrate of the surface of the channel will be someplace in the folds of her work so you miss. Particular work we call it surface champ we just we mobilize the for the bottom of the class I thought both on the channel which is Colossus The allows easier surface chemistry that our way. We use a surface chemistry from Team Heath group that's supposed to are they with a high density and then we have to say manner of things we follow the meeting fragments in and that their way to Washington or in more than our specific goals option and that they way that Jass the whole and that to gather D.N.A. with a lot of the D.N.A. prepared to allow every OK. The good news is up obviously we found it through and so these are the data I think one thing we are exploring is that also to use it to profile vacation like each story twenty seven I mean three this is generally. Regarded as a harder to profile he's the mother the reason is that if you look at the feature H three K. four I mean story you're largely see the scene the reader peeks that are fairly sharp fairly tall. In the saddle and you know how these brawler the peaks they're all connected to Gander this whole thing is can see the peak and then they are fairly low to you know only why or how a very low background than your able to tell this is the peak so I'm glad that we were able to do that through I think of that young coded data is what we put a reference to this is water that they tell people collect data using ten million cells using the combination No you know approach you can see we are human using one hundred cells five hundred cells we offer a better signal to noise ratio compared with their data. We also obviously comparative to the Motor Vehicle reach you know how the bees probably bigger surface area and that we see actually Same with our performance here. The surface here but obviously at this point it basically just require a single channel to do that say you know how are channel your follow the solution. To the things in that they have that I say done and the so if you put a label being system in there then there are lousy to. Prove you can also function is the surface was there for his full marks then you can use the same thing was to look at there for his full marks so in this case we tried our Fortran Otherwise we also tried the H. and O. the Weiss You can see there is no crosstalk between these channels and the you how the replication. Wrapper locates you know why you're trying to do the same C. to look at the same face for mother for creation OK so. That's what we did the case for modification so we also there were a lot of the wise unpack knowledge for the emasculation So I want to hear on a better tool about how to look at Pima solution using a technique called by the sequencing OK so that the solution this is established the. Approach to do by itself and sequencing what that means is kind O. I.P.G. now I think change now is that whether the site or scene is a minefield or at this point so what people found is that if you are treated using chemical by Sol fight it's actually by itself I sold him a sodium by saw fight then I mean. If the federal scene as a parish to a Mathilde group then that doesn't change if the center scene is not how it is not a mass on a table. You're a cell after the amplification that the whole thing becomes a P C So basically your car working there my thought lesion status into the sequence information after that you basically just need to do the sequencing they are compared to the origin no in the reference genome. Or our your C. are the C. becomes a key you know how our. Side R.C.I. had our location so the masses are all for a single new kind of higher resolution you know if you're sequenced deep enough you can pile each and every in the nuclear high that there are there my solution state health is you know again the problem is that your the need or several micrograms of D.N.A. that's allowed ourselves to generate such information. And one bolt of America. Is that that the by Solve the come up. Loses a lot of D.N.A. just of the straw is of the D.N.A.. And that then they cannot be seen they were in a sequencing and that require a lot of D.N.A. to start with this. So before I got into the details of how we do the. Come under the bias of a sequencing I want to measure Jan our problem for microfluidics dealing with is more like an about bad that's. How you would add that in your agents from one to the odder because if you recall that if you're doing this molecular biology in the branches Gail you will just have and they keep writing things to it and the save for micro floor they see enormous now. One chambre if I have things to it that's going to fly to the So they are for each and only in their outer So you're losing my period that way so there is a one way to solve that problem that was in the earlier work. That was also subsequent to use the in the commercial products from flu virus. Is that you know how a bunch of chambres attach the charter. To the beginning of the process when there were other reagent to open one of the chambres of the. Astra Wallie I'm now you can put the chemical in there without losing the previous chemical certainly the problem there are two problems one is that if you know how many you need to add many chambres in. More and more complex Sagen the. You need to be careful about the interference different regions cuz of the rage of the Orioles in the first of may not be compatible with the region. So that they will be in mind makes of the gather so the. Way they are why the sort of problem is that they couldn't use chemical analysis of the cells that you'll thermal ices which is incomplete. But they label the real and then they also need to sign the Chambre size so that they have a proper that Lucian so that the later region doesn't that the earlier read age into doesn't strongly interfere with the leaders that so we have thought that that's a general problem if we won the treatise a new career as is from our table stamps of the. Work in a we thought maybe we we want to think of something better than that you know so in this case we're fairly simple the Weiss. Complicated by twenty. Periods are only their reaction chambre I had to send her and they saw attached to the Can we call noting chambres the size and the connection between the reaction chambre and the loading chambre can be. Established by operating these walls that's all they say is we realize that. There is a gigantic difference in terms that they feel safe with criticizes and other smaller. Rage and like ions or not you know. Deal with two fifty. Which is not a worry big of you fragments we're talking about swore a magnet you'll get there for us even if you're saving compared to ions on the small molecules OK what I mean is is you can imagine doing the diffusion. Rage and takes change that the DA will largely if they in the reaction chambre. Because they feel they're so slowly but the small islands would be able to quickly catch into the loading chambre and the small islands or small molecules in the loading chambre will be able to get into their reaction time for you on the same period so they did some modeling to prove that's the case and. So the process works like this when we come. Here this is a cross-section of you otherwise so the center one is the reaction. To the tremors on the science or. So we will the force will start approaching that the interaction chambre and that then we can close over the walls between the reaction chambre and loading chamber now there by itself. With a be able to the fields into the ration chamber and of the D.N.A. with a large they there your software or small. Person there was something you know that badly do by itself either come worse and then that's its cause of this these solve formation. Which And again you can sort of this is a. KILL YOU CAN THEY feels that seen through the reaction chambre and often if done. By diffusion again this time yellow the water in the loading term for the cat out because what are you preparing the subsequent Babs. Needs to be Gatorade up to and by doing all that we found that we are much more D.N.A. than that the coal. That actually it was pretty cool with a they tell you in terms of looking at the D.M. isolation. That are going to go into the details here but that we you know people using thirteen and a gram of D.N.A. they were trying to eighteen they were occurring only point nine maybe in the C P G M isolation features and then we can. Easily. You know one point a final meeting of these features using a three and a gram so we're doing much better. Much better information using much less the and the more importantly we are twenty covering that being with small car reach more more the sequencing so that to this is March higher confidence data for to work with. So the last part of from a talk is to talk about some biology you know and the magical unified theory of the scar were using these technologies because I want to really show that the we can work with space in the materials we can establish South have a specific command there and that we can. To really information or biological you size that that's potentially interesting in the U.S. for and. So one thing one direction I have in my lab is to look to the brain how data functions and the HOW that you know genomics the. Facts of the brain functions and the brain day while point. Because in the earlier in the talk that the brick here eighty people really However. Is highly involved in their so you know this particular project we are looking at different parts so most the brain we look at the prefrontal cortex we look at cerebellum OK the cerebellum generally people believe this is the location for mold hole here if he is in the moment. And the prefrontal cortex that's the place for responsible for the nation and the planning OK so they have drastically different of functions we want to see whether you know we can see some difference in the I.P.G. you know so we isolated the tissue. And that then we would China nuclei and then we'll facts. From clears the supporting South type and then we come profile the IP genome for these two different types and you can see sort. Of the. Neurons from prefrontal cortex and the organs from that. It's interesting that the neurons in there from place is. Very different genomes so that's sort of gives you some hints about how they're more like you're a basic. Supports the that they are for us in the functions and also virus was there for at least all marks you can see for example for each three K. four I mean three this is a correlation in no matrix if a loose brood that means they have a high correlation amount of data sets so you can see in that case. A fairly good uniformity across the different types of cells from different location of the genome. It's much more differentiating if you look at the art or tool case the marks so that's the address of these to his or marks are probably more closely related to that they are friends in the function of the location in the that I care about E.G. So that's one. Project to read there that the art of thing we look at also related to brain is that. We want to see how do you know under the psychotic drug facts of the. Genome. Because for example I have P.T. nomic chanties has us back to the month of the season X. schizophrenia. And euen so sort of in you know that unpaid psychotic drug or how. We use the symptoms so you wonder how they help so we feed of the mice character the mice are truly using the. Drug called commos impune and. For fairly long period of time they will look to deem isolation profiles from the treated the mice the house six treated in my. Biased see. How the mice indicted only by the vehicle using the vehicle these are to control. So then we can figure out some difference between the two groups in terms of my summation we found the file hundred modern five hundred locations that are in the genome that they are different and that we found that are. Genes related you know how been proven to be related already involved in. P.T.Z. it's so so I think the implication from this data why is that. The under psychotic drug probably improve the symptoms by interacting with you know so I can do. That or it's a cautionary note about why or for example. The post-mortem of human brain some polls you need to be careful to differentiate the. Changes introduced by the progression were source of the genomic changes introduced by the drug because the patients probably took some drugs when they were alive so so you really need to be careful when you do such and novices lie or trying to find the country for comparison so. So they are did you actually. Pay genomics in the Certainly I mean one per track that we're now going to look at how our meal tasted like B.R.C.A. one changes. Our hypothesis is that a mutation like B.R.C.A. one with a sort of lay the ground. For the sort of. London scape that makes the. More likely compared to the. Wild type comparison. See you one mutation so the B.R.C.A. one is that your tumour surprise or. Teen. Teen. You know if woman has a B. or C Y mutation then there is a seventy percent chance for the woman to look at bras accounts are forty four a person their chance to get home or cancer so this mutation is really made a famous by the per one hundred two in the surgery you know by the. Early I guess you know already two cells or so were years or so so this is a famous mutation sort of way and that the way we. Wade through I mean the pre-concert Taishi was that I mean the sort of the patient doesn't how any kind sir at that point maybe when they're young so this is from the cosmetic surgery. That we can edit out the breast tissue and the because our technology allows us to work with a small number of cells we can be wide of the cells into four fractions you know. That's more true. Janitor so draw most cells because all cells and then if you look at the Crystal modification they have her here you can see that. We have the B.R.C.A. one mutant compared to the wild type you can see that they largely look same or in terms of peaks a location number of peaks with a big subset of these highlighted area highlighted. Spitefully following up or janitor you can see sort of the B.R.C.A. one meal to meal ten looks on a bit there front and. You see some of their friends there. But you know certainly there are there's a lot more difference if a compare among the different South types so if you can sort of look across their roles and. And that then sort of again this is a correlation. Of the left there's a correlation matrix with there you can see you can roughly group. Some poles of the same South higher plane to one in the WHERE THEY ARE you know the square surrounded by this what I can frame and the area surrounded by this yellow frame that's that's really the mutinous sample B.R.C.A. one Milton sample you can see you know from the you know if you look at the genome and I will correlation it's hard to differentiate that are from the from the wild type samples but if you look at it more closely those will be debate on the right. Individual. You can find these locations that are mutants which indicated by the yellow line underneath the column and that. Is the black line and they're nice to the column and. So you can see for baseball cells for example the six thousand six sixty four hundred the locations that you know how increase of the. Cave from this I always see seven hundred locations is a decrease the signal you know for normal progenitor your house and of these size tool for the art of South house why of the storm or sell you know you needed to realize So you see a much bigger number of the sites being their friend in that it's crazy how twenty three Sauza And you know size being having a decrease of the you know. You know you know just just why a compared. With the be able to hunt and then the art of South how more true your house generally wire feels sites that are different. And the militant and and the wild type so that in general tassel sort of differing involvement to different roles played by these different South types so we're still piecing out the art of information to get or you know to hopefully to form a complete picture. To see if we can prove the it's our hypothesis and to summarize I guess hopefully I show you that it's important to do the profiling R.P.G. no. Specific manner but why you try to do that or a requires you to work with a small number of cells. That are microfluidics per why it's such a private from to do put houses and also with higher throughput you know and. One thing I want to I got five. In general certainly people talk about single cell analysis these days a lot. But in general you can generate much higher quality of data if let's say you work for thirty cells and they use all of these sorties sawzall January one profile where you'll single cell have knowledge to produce a thirty data science then patch them take at or the reason is obviously you need to do bar coding and all of that kind of things that loses a formation and cannot recover later and then that decreases the. That they have quality So if you're south Bailey pay is not creating or for you it's almost always a better relative to go in terms of data quality to do what we call a low importer see that our single cell I.C.. Is that I will consolidate Coleridge hurdles I think being worked. It is a number of nations and when I come up biologists there from pro-drug side of things certainly Carlson learning things from the dumb you know they'd be poor why the polls for us I think. Highlight the we see you working on the poor in who member IN THE MONEY how the seas are rolling is a breast cancer you know B.R.C. you are mutation and I also work with T.N. and the kind of high end these are buying from occasions for that whole novice is under so long there are people I work with for example so in. On the C.T.C. we started somewhere for looking I see it he sees you know she's a sport on C.B.C. isolation a wee wee haue some project there looking at the book burning highness or a Working with Madame E. at the Stanford you know and we also work on a bit of Champ working with Julia. I thought Northwestern and I also on our funding from different years think you'll solve. H.. So we. Would be happy to either take any questions. Or you. Know. Yet who. Who. Do. Your circular. Saw for sure whoa I think this so far are certainly show that will be using facts a lot I think it for the worse of them doubt that's good I think a surface marker that's one type of female popular. But there for example if there is an art or current here you know how certainly regardless how ill how the cells. How a sizable group that we can do the subsequent stop so profiling that peach you know and like like how Martian though I think that's right no one here is data. How meaningful isolation is a fall particular biological class when you know if you know the pending all you know how how cool that isolation is of all particular biological problem then. Make a profile is yours for not you'll fall once we generate that but what that is sort of only works where while with what her work sorting stop you how before that but not supposed to happen you know upstream. You know for sure. I think it's sort of the way we kind of. First of all you know how these South How is that the HOW DO YOU HAVE A is a poverty is a beta. I think it's sort of first of all we need to Wily that our technology for us in that case the past. And their common condition like I are but the else then my childhood that they tell you how was are but they else for example offer you the formal chair they say OK we've got the same data. So you can do a correlation between your data and that their data just by putting beans in their genome sort of the then that's just across correlation of that so if you know how a very high correlation. Source. You know you'll have to assume that. I guess I mean first of all it doesn't matter it's homogeneous or not I mean if you know how reproducible makes sure they are supposed look at the same profile OK. In. School they scout scene from the whole merge to Jeannie if they and but they want to have that data you'll say OK my might have knowledge attacks out and then they walked or were. There they'll say OK well however I have a scar on I need to believe in that but certainly there are certain criteria for example for each story came for I mean story normally people with a find the same twenty thousand peaks I think it's a pretty wide the winds to deal probably anywhere from seven thousand the true thirty cells in the would be reasonable if I run feel it's reasonable if you know how side one hundred something's wrong you know if you know how file solves and something's wrong you know so you'll have some general idea once you see the data at the art of thing is certainly the reproducible Bailey paper between the ripening case if you know how I reproduce a baby the bear I mean you have for a. Whole you know. I think I can trust that. Sure for sure. Right that's that's that's. I think it certainly has to they're part of that how you do those sorting and the south. Correctly there I think in Britain happens to be aware of the situation because the late or early you can say Irene you're wrong it's there for an hour and because of their location because their connectivity. If you really want to wear or find a resolution. I mean there is no limit to that you're sort of I think of why approach would be actually doing thing with our analysis there basically in that case you're gathered data from a bunch of cells they all say I cannot differentiate these cells based on surface marker there is no cool surface marker either but now I how this IP genomic data for you to cells I can you'll see that taste takes. You into groups therefore these each group I plan to believe this is wild subtype and that. You basically isolate the south have that away. That's really the profiling in the lobby for profiling so. More and more complicated certainly but but brains certainly of virus Barsel organ say that if you know how a tumor it hey sure maybe you're not as Sun City you DO YOU ARE thing is for example let's say you care only about tumor cells but by your house I mean if you're treating you know email cells in there also allow us to the tumor cell is the let's say a person tell the cells they are talking about then they are going to show it's a number of scame sequencing IRA cell provides one copy of the genome and I mean if you're providing. Marcel's that's going to show up March better than. You know you mean yourselves. So I think. They are hanging on the situation. I was a problem sort of in the we surely you know these are certainly relevant considerations. Yeah you know. Right. A reason is that. Prior to the laboratory your house fixation process there. For gays is gnarly near and. Fertile a way. To beat a collection I mean even on the table it may not be entirely a linear process either meaning that you may not take it you know ten times more. If you have ten times more cells to start with I think our experience has been that. If you're prime to extract the smaller percentage of the chance of being a why or how a bigger number of cells so I think all you things country be able to so you don't how a leaner. Leni or. Process there I think of that's a random when the point is that. Why you know compared to use profiles certainly you want to do these polls. In the same fashion meaning if who is one thousand cells for tumor they are compared to the surrounding tissue you're better used by cells and cells for the teeth a shoe tool in so that in the end they you if you're see that peak of this appearing that that's a real thing you're. Yeah there is no intrinsic limit I think of what time I should there was. To prepare a laboratory you need a ton of The anyway why me to do that is you know collect the D.N.A. from different samples they are barcode of the different samples they're friendly and they'll pull the B.H. I gather took gave you that twenty people gram they have come forward or push the the amount how each some holes to you want to lower a smaller number but certainly if you need to do that bar coding you probably lose some D.N.A. If you're into our process so that there is some compromise there but intrinsically there is no. Limit I think that the limited way see is that. How how low you can go and this deal will be enabled to generate heels for information for example even the case so the single cell chamber Sica experiment they had to have a field just generate a thousand rays it's why are hard to analyze the data you no longer see the peaks and it's basically warily information cowards. Later fraction of the genome Soledad to just. Being useful at that point but I don't know if you can. Clear cut a line somewhere what he is useful for they data published in Nature about her knowledge. Care and that they were able to differentiate different types just based on that the one solved the race so so I think they pending all of the. Ask you know. Thank you.
