Applications of Cryopreserved Human Dissociated Tumor Cells (DTCs) for Drug and Diagnostic Development

The acquisition of fresh human tissue is often an impediment to significant research advances. As an alternative, Discovery Life Sciences offers cryopreserved human dissociated tumor cells and tissues as a viable specimen source for many downstream applications, including immunophenotyping, bulk and single-cell sequencing and single-cell functionality. Extensive cellular profiling of these samples by flow cytometry revealed indication-specific trends in the composition of the tumor microenvironment. Additionally, these specimens provide the opportunity to screen for novel biomarker expressions including the expression patterns of the programmed cell death protein-1/ programmed cell death ligand-1 (PD1/PDL1) pathway.

These dissociated tumor cells are amenable to the 10X Genomics single cell pipelines, and workflows have been established to optimize sample preparation into these assays. Finally, as viable cell suspensions, dissociated human tissues can be utilized in both short-term and long-term cultures, and the functionality of tumor-infiltrating T cells can be evaluated using IsoPlexis single-cell proteomics pipelines. Collectively, cryopreserved dissociated human tissue allows for multifaceted analysis of the next generation of cancer therapies.

Shawn Fahl, PhD, VP Lab Operations, Cell Services & R&D, Biospecimens, Discovery Life Sciences

Dr. Shawn Fahl is a skilled immunologist working to advance the cellular analytical pipelines and R&D laboratory processes for Discovery Life Sciences. Dr. Fahl received his PhD in microbiology from the University of Virginia in 2013 where he studied transcriptional control of B cell development. He continued his training as a postdoctoral fellow at Fox Chase Cancer Center from 2013-2017, where he focused on genomic regulation during gamma/delta T cell development. An expert in flow cytometric analyses evaluating lymphocyte biology, Dr. Fahl joined Discovery Life Sciences in June 2017 to advance the analytical workflows for many product lines, including dissociated tissue cells and isolated cell products from apheresis. As part of these efforts, Dr. Fahl has overseen the dissociation and flow cytometric analyses of over 4500 tissue samples and the implementation of single-cell genomics applications for dissociated tissue. Dr. Fahl has published numerous research articles in prominent scientific journals and presented at national and international conferences.
