摘要

Gastrulation, the step that follows blastula formation during development, consists of the separation of the three embryonic germ layers, namely ectoderm, endoderm and mesoderm. Vertebrate animal models have revealed highly conserved mechanisms of endoderm morphogenesis and determination (Kimelman and Griffin, 2000; Grapin-Botton and Constam, 2007). Following establishment of the endoderm, complex morphogenetic movements and crosstalk with mesodermal tissues lead to an endodermal gut tube with an established anterior-posterior (AP) axis and several progenitor domains that will give rise to the parenchyma of endodermal organs (thyroid, lung, pancreas, liver, gastrointestinal (Gl) tract). Although our understanding of endodermal differentiation has greatly advanced in recent years (Zorn and Wells, 2009), several gaps in our knowledge remain concerning the specification of endodermal progenitors.
