Member, JCCC Cancer and Stem Cell Biology Program Area

Scientific Interest(s):

Dr. Bennett Novitch is interested in molecular mechanisms that control the proliferation, identity, and differentiation of neural stem cells.

Novitch's laboratory research aims to understand how neural stem and progenitor cells give rise to the vast array of distinct neuron and glial cell types found in the central nervous system during embryonic development.

To study how this process works at a molecular level, his lab is primarily focusing on the formation of three cell types: spinal motor neurons and intemeurons, which control the movement of muscles in the body, and oligodendrocytes, which support the function of motor neurons.

Novitch's main objectives are to:
  1. Identify the extracellular signals in developing embryos that instruct stem and progenitor cells to form these and other cell types in the central nervous system
  2. Ascertain how these signals regulate the expression and activity of transcription factors within stem and progenitor cells
  3. Ultimately determine how these transcription factors control the division, differentiation, identity and function of neurons and glia.
Insights into these fundamental mechanisms are essential for determining the role of stem and progenitor cells in normal development and in diseased states such as cancer, as well as for developing methods to manipulate stem and progenitor cells to facilitate the repair of damaged neural circuits.
