Meeting Abstract 47.2  Sunday, Jan. 5 10:30  Gastrulation and the fate of the blastopore in the snail Crepidula fornicata LYONS, D/C*; PERRY, K; HENRY, J/Q; Duke University; University of Illinois, Urbana-Champaign dcl.duke@gmail.com Gastrulation is a critical morphogenetic process in metazoan development by which presumptive endoderm and mesoderm cells become internalized. Modes of gastrulation (e.g., ingression, invagination, epiboly) […]
