Webinar Description:

Cancer heterogeneity represents a critical obstacle to efficient therapy. We have previously shown that mutually exclusive genetic sub clones can coexist and play different roles in growth of brain tumors and that metabolism of tumor cells depends on their microenvironment. Cancer cells can also manipulate normal stromal cells to provide necessary growth factors. In addition to genetic heterogeneity of cancer cells, molecular profiling of the whole tumor can be skewed by the presence of variable stromal and inflammatory cell subpopulations. To separate cancer cell, stromal cell and inflammatory sub clones and dissect their genetic and epigenetic heterogeneity, we implemented DEPArray system, a microchip-based digital sorter, which enables us to distinguish cells by fluorescently labeled antibodies and DNA content and isolate pure, single cells or homogenous subpopulations from fresh or archival pathology samples. Downstream analysis includes DNA and RNA next-generation sequencing and methylation profiling on a single cell level. Using dielectrophoretic capture and digital sorting, we can investigate genetic and epigenetic heterogeneity of cancer cells with unambiguous determination of sequence variants, loss-of-heterozygosity, copy number variants and methylation. We can further investigate epigenetic and transcriptional changes in tumor-associated stromal and inflammatory cells and dissect how cancer cell growth and spread depends on non-neoplastic cells.

Learning Objectives:

  • Understand the role of DEPArray in resolving genetic heterogeneity in cancer and obstacles in analyzing it
  • Investigate the different methods of sample preparation leading to precise genetic analysis
  • Evaluate all the potential downstream analysis for captured 100% pure cancer cells


Matija Snuderl, MD

Director of Molecular Pathology and Diagnostics

Department of Pathology, NYU Langone Medical Center and Medical School

Dr. Snuderl is Assistant Professor of Pathology and Neurology and Director of the Molecular Pathology and Diagnostics at NYU Langone Medical Center. He obtained his MD degree from Charles University, Prague and completed his residency in Anatomic Pathology and Neuropathology at Massachusetts General Hospital. He then completed fellowship in Molecular Genetic Pathology at Harvard Medical School and post-doctoral fellowship at the Edwin L. Steele Laboratory for Tumor Biology at Massachusetts General Hospital. Dr. Snuderl joined the faculty at NYU Department of Pathology in January 2013 and has been actively involved in designing novel molecular tests and platforms particularly in molecular neuropathology and epigenetics. Dr. Snuderl has strong interest in tumor genetics, heterogeneity and microenvironment. The American Association of Neuropathologists awarded his work with the Lucien J. Rubinstein Award for the Best Paper on Neuro-oncology in 2009 and 2015 and Honorable Mention in the same category in 2008 and 2010.
