Guest:
Dr. Carole LaBonne is the Erastus Otis Haven Professor of Molecular Biosciences at Northwestern University. Her lab studies the genesis of neural crest stem cells at the level of the signaling pathways and transcription factors that comprise the neural crest gene regulatory network. They also study how these mechanisms contribute to exit from pluripotency and the subsequent lineage restriction of neural crest cells to their derivative cell types that collectively define vertebrates.
