My laboratory models and studies the development of the nervous system in a culture dish. We have pioneered some of the most efficient methods for the differentiation of pluripotent embryonic stem cells into specific subtypes of spinal motor neurons and interneurons in vitro. The process faithfully recapitulates normal embryonic development, providing a unique opportunity to study neural development at a biochemical level in a controlled environment outside of the embryo.
We combine the differentiation system with CRISPR based genome editing and inducible expression of transgenes to decode transcriptional programs controlling progressive transitions from a pluripotent stem cell to a defined postmitotic neuron. We are constructing a global map of genomic sites bound by cell type specific combinations of transcription factors and study how these regulatory elements control expression of distal genes. The ultimate goal is to use stem cell technologies to decipher the syntax and grammar of the "language" used by transcription factors to specify neuronal cell identity during embryonic development.
Finally, the lab capitalizes on the unlimited source of spinal neurons to study molecular processes underlying neuronal maturation, synapse formation, and neuronal aging and degeneration. We are using both mouse and human pluripotent stem cells to model motor neuron degenerative diseases, such as amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease), with the goal of discovering new drugs for these currently untreatable, devastating conditions.
Hynek Wichterle is an associate professor holding a joint appointment in the Departments of Pathology & Cell Biology and Neuroscience (in Neurology) at Columbia University Medical center. He received his M.S. degree from Charles University in Prague and his Ph.D. degree from The Rockefeller University. He trained at Columbia University, where he became assistant professor in 2004 and associate professor in 2012. He serves as a co-director of the Columbia Stem Cell Initiative and as a Vice-Chief of the Division of Regenerative Medicine in the Department of Rehabilitation & Regenerative Medicine.
