Dave McClay : Gene regulatory networks as tools for understanding embryonic development

The job of embryogenesis is to diversify cells into the hundreds of specialized cellular functions required by an animal or plant and to place those cells in the correct location in the embryo. To accomplish that complex job transcriptional regulation provides control circuits directing each dichotomy, each cell movement, and the patterning of cellular assemblies so that the animal that emerges from embryogenesis can feed and perform the necessary functions for survival of the species. The questions being addressed in this talk are to ask how gene regulatory networks are assembled, how do they change with time, and how do they accomplish the enormous regulatory task needed for building an embryo.
