BD Biosciences

Presenter:

• Christina Chang, Ph.D., Senior Scientist

High-throughput single cell RNA sequencing (RNA-seq) has recently emerged as a powerful tool for profiling complex cell populations. While traditional RNA-seq captures information about transcript expression, recent technological advances using oligo-conjugated antibodies enable simultaneous detection of protein alongside RNA in high-throughput sequencing. This technology enables high-parameter protein analysis, and addition of protein information to RNA-seq data can provide better resolution of markers with low transcript abundance. This also enables more precise cell type identification and more intricate separation of cell types in a complex system. Ultimately, combining information from whole-transcriptome RNA-seq, targeted gene panels, and protein profiling (BD^® AbSeq) can generate novel insights into single cell biology. Here, we discuss the interplay between single cell sequencing multi-omic data and other technologies, as well as how best to harness the information gained from high-parameter single cell sequencing data.

STEMCELL Technologies Inc.

Presenters:

• Colt Egelston, Ph.D., Staff Scientist, Dept. of Immuno-Oncology, Beckman Res. Inst., City of Hope
• Vesna Posarack, M.Sc., Scientist

In some cancer types, the presence of tumor-infiltrating lymphocytes (TILs) predicts the response to chemotherapy. However, more work is needed to better understand the composition and functional state of TILs across cancer types and design more effective immunotherapeutic strategies. Dr. Colt Egelston and colleagues from Dr. Peter Lee’s laboratory previously demonstrated that CD8⁺ TILs in many breast cancer samples retained polyfunctionality despite expressing PD-1, a marker of T cell exhaustion. In this workshop, Dr. Egelston will discuss recent efforts to isolate and characterize phenotypically and functionally exhausted CD8⁺ TILs from a subset of breast tumors. His work suggests that some patients have inflamed tumors infiltrated by exhausted CD8⁺ TILs and that these patients may benefit from immunotherapeutic intervention. STEMCELL scientists will discuss other applications and cell types with which EasySep^™ cell separation technology can be used to accelerate cancer research.

Recent advances in single cell analysis and instruments, in parallel with next-generation sequencing, have enabled the generation of transcriptomic data in a high-throughput fashion, propelling the field of single cell RNA sequencing (scRNA-seq). However, despite the analytical power of scRNA-seq, important hallmarks of immune cell states, phenotype, and other cellular processes that heavily rely on protein expression are often not detected in scRNA-seq. In this workshop, we will describe recent developments in the use of TotalSeq^™ oligo-antibody conjugates as these reagents integrate seamlessly into workflows that combine scRNA-seq and protein analysis, such as CITE-seq and REAP-seq. We will illustrate how some flow cytometry experimental complexity can be simplified with the use of these reagents, reducing the number of populations that need to be sorted before single cell analysis. In addition, we will show the use of cell hashing reagents, which enable sample multiplexing, resulting in reduced variability, lower cost, and optimization of single cell instrument and reagents use. Hashing antibodies can also be applied to nuclei, not just single cell suspensions, for cells that are difficult to isolate. With the development of the TotalSeq™ reagent suite, we hope to facilitate the next wave of legendary discovery in biomedical research.

Beckman Coulter

Presenter:

• Nancy Dempsey, Global Product Manager, Research Flow Cytometry

The accuracy of multicolor flow cytometry is improved by eliminating dead cells from the analysis. Dead cells bind antibodies nonspecifically and also tend to have increased autofluorescence. Completely eliminating them by forward and side scatter is difficult because dying cells can maintain their physical structure at the beginning of the process. All commercially available fixable viability dyes are based on NHS ester compounds that crosslink with primary amines on proteins. This chemistry is susceptible to hydrolysis, decreasing the reagent stability, and ease of use. ViaKrome Fixable Viability Dyes are a new thiol reactive fluorescent dye that is soluble in aqueous buffer, does not require DMSO for reconstitution, and exhibits bright staining in whole blood samples. They are offered in a range of colors: ViaKrome 405, ViaKrome 561, ViaKrome 638, and ViaKrome 808. This choice provides flexibility for multicolor panel design. The compatibility of the ViaKrome dyes will be presented in eighteen-color immunphenotyping panels and functional assays using PBMCs and whole blood. For research use only. Not for use in diagnostic procedures.

BioLegend

Presenter:

• Kelly Lundsten, Business Segment Manager Advanced Cytometry

The Cytek^™ Aurora flow cytometer has made more than twenty-four color flow cytometry panels possible with only three lasers. The spectral overlap of traditional fluorophores previously limited panel design. With spectral unmixing, fluorophores may occupy the same emission peak if each has its own distinct spectral fingerprint. This new generation of instruments also use photodiode detectors instead of traditional PMTs and are sensitive up to 1000nm, making it now possible to detect novel near-infrared emitting fluorophores. This talk covers spectral unmixing, informed panel development, and a twenty-four-color immunophenotyping panel implementing some novel fluorophores developed by BioLegend, specifically useful for this new generation of flow cytometers.

CRISPR technology has revolutionized stem cell biology research in recent years, but applying it in primary immune cells has proved challenging. In this workshop, Dr. Shifrut will present a novel pooled CRISPR screening technology developed in Dr. Alexander Marson’s lab. The Marson lab is interested in using CRISPR technology to prioritize novel targets for cancer immunotherapy drug development and to improve the design of genetically reprogrammed cell-based therapies. Using this new method, known as sgRNA lentiviral infection with Cas9 protein electroporation (SLICE), the lab identified key regulators of primary human T cell function. Targeted ablation of individual candidate genes characterized hits and identified perturbations that enhanced cancer cell killing. These results highlight the potential of SLICE to explore unmapped genetic circuits in primary cells and to guide the design of engineered cell therapies. STEMCELL scientists will also discuss other CRISPR applications.
