Meeting Abstract 87.3  Monday, Jan. 6 10:45  Notch signaling may have evolved to control cellular differentiation and growth during development of metazoan animals LAYDEN, MJ*; MARTINDALE, MQ; University of Florida layden@whitney.ufl.edu The emergence of multicellular animals possessing distinct differentiated cell types requires a mechanism to regulate the cellular decision to differentiate or remain undifferentiated. Notch is a […]
