8:30 FEATURED PRESENTATION: Profiling Protein Heterogeneity with Precision Single Cell Immunoblotting

Amy_HerrAmy E. Herr, Ph.D., Lester John and Lynne Dewar Lloyd Distinguished Professor, Bioengineering Investigator, Chan Zuckerberg Biohub, Bioengineering, University of California, Berkeley

We have introduced a new class of ‘electrophoretic cytometry’ tools that increase target selectivity beyond simple immunoassays. Enhanced selectivity is essential for targets that lack high-quality immunoreagents – as is the case for most protein forms (proteoforms). In fundamental engineering and design, I discuss how the physics and chemistry accessible in microsystems allow both the “scale-down” of electrophoresis to single cells and the “scale-up” to concurrent analyses of large numbers of cells.

9:00 Considerations for High Dimensional Immunophenotyping of Clinical Specimens by Mass Cytometry

Elma_KadicElma Kadic, MSc, Senior Scientist, In Vitro Pharmacology, Merck & Co. Inc.

This talk discusses validation steps that were taken to assess applicability of highly multiplexed mass cytometry analysis of single cells, with the ultimate goal of using this technology for biomarker discovery in clinical patient specimens. Case studies of renal and colorectal carcinomas will be presented.

9:30 High-Resolution Lineage Mapping of Myogenesis by Single Cell Mass Cytometry

Ermelinda_PorpigliaErmelinda Porpiglia, Ph.D., Scientist, Microbiology and Immunology, Baxter Laboratory for Stem Cell Biology, Stanford University

During muscle regeneration, cell state and identity change dynamically over time. Here we capitalized on a transformative technology, single cell mass cytometry (CyTOF), to identify in vivo skeletal muscle stem cells and novel progenitor populations. X-shift clustering analysis paired with single cell force-directed layout visualization of the myogenic compartment, resolved the intermediate stages of myogenesis at an unprecedented level of detail, revealing the complex relationship between stem and progenitor states during regeneration.

 Nexcelom10:00 Validating and Optimizing Single Cell Sorting of FACS Using the Celigo Image Cytometer

Wenyi Chen, Ph.D., Field Application Specialist, Nexcelom Bioscience LLC

Currently, single cell sorting is validated via microscopy, but manual observation is highly tedious and time-consuming. We demonstrated a high-throughput detection method to validate single cell sorting using the Celigo. The image cytometer was used to detect a single calcein-AM stained Jurkat cell sorted into 96-well microplates. The sorting efficiencies ranged from 90 to 96%. The proposed method is important to flow core laboratories and users for confirmation of single cell in each well.

Junyue_CaoJunyue Cao, Research Assistant, Jay Shendure Laboratory, Genomic Science, University of Washington

We developed a combinatorial indexing strategy to profile the transcriptomes of single cells or nuclei (sci-RNA-seq: Single cell Combinatorial Indexing RNA sequencing). We applied sci-RNA-seq to profile nearly 50,000 cells from the nematode Caenorhabditis elegans at the L2 stage, which is over 50-fold “shotgun cellular coverage” of its somatic cell composition. These data generated by sci-RNA-seq constitute a powerful resource for nematode biology, and foreshadow similar atlases for other organisms.

Aaron_StreetsAaron Streets, Ph.D., Assistant Professor, Bioengineering, University of California, Berkeley

Microscopy and RNA sequencing are both precise techniques that can be used to quantitatively profile single cells. However, in order to infer the relationship between gene expression and morphological phenotype, it is necessary to image and sequence the same single cell. We use a microfluidic platform to couple imaging and RNA sequencing of single cells and present recent developments in analysis of large, multimodal, single-cell datasets.

5:15 Characterizing the Complexity of Cell Populations with Sequencing and Magnetic Levitation Technologies

Raeka_AiyarRaeka Aiyar, Ph.D., Director of Communications and Development, Stanford Genome Technology Center

We have developed several single cell technologies to advance our understanding of the molecular systems driving developmental processes, tissue differentiation, immune responses, and disease onset. These include RNA-seq methods that have proven efficient in a variety of cell types and in characterizing T cell repertoires. We have also developed a novel, smartphone-compatible magnetic levitation platform capable of marker-free visualization and isolation of rare cells for downstream phenotyping and diagnostic applications.

Sanjay_KumarSanjay Kumar, M.D., Ph.D., Professor, Departments of Bioengineering and Chemical & Biomolecular Engineering, University of California, Berkeley

Tissue behavior is often driven by a few cells within a larger population, creating a need for single cell analytical tools. We have developed technologies to probe the structure, mechanics, and motility of individual cells, with an eye towards integrating these technologies with molecular measurements. I focus on the use of microfluidics for high-throughput characterization of tumor cell mechanics and invasion and single cell micropatterning to investigate heterogeneities in cellular structural networks.

9:00 Profiling the Somatic Variation of Thousands of Single Cells Using Combinatorial Indexing

Kristof_TorkenczyKristof Torkenczy, Research Scientist, Andrew Adey Laboratory, Department of Molecular and Medical Genetics, Oregon Health & Science University

Quantification of somatic variation within heterogeneous cell populations remains challenging. Bulk approaches fail to disambiguate low-frequency mutations. Single cell genome sequencing provides an accurate means of somatic CNV detection. However, current methods are limited by throughput. To address this, we have developed a novel multiplexed single cell protocol that uses combinatorial indexing to increase throughput and applied it to find subclonal mutations in a PDAC tumor, uncovering multiple tumorigenic events.
