Abstract

Integrating Organ Induction During animal development, multiple signaling pathways specify the induction of organ progenitors such as those in the pancreas and liver. Wandzioch and Zaret (p. 1707 ) investigated how three signaling pathways converge on the earliest genes specifying these organs. Within hours, multiple changes were observed in the inductive network with different signals operating in parallel. The findings may help to explain the incomplete programming seen in various stem cell differentiation protocols.
