The organizer is a region in gastrulating embryos that induces and patterns the body axis. New research shows that induction of organizer formation is regulated by interplay of inducing and inhibiting ...

In warm-blooded vertebrate embryos (mammals and birds), the axial tissues of the body form from a growth zone at the tail end, Hensen’s node, which generates neural, mesodermal, and endodermal ...

Time-lapse analyses of normal cellular behaviours and signalling by fibroblast growth factor (FGF) provide new insights into the cell motions and molecules that form the posterior nervous system. The ...
