To study the developmental origin of the pancreas we used DiI crystals to mark regions of the early chick endoderm: this allowed correlations to be established between specific endoderm sites and the positions of their descendants. Endodermal precursor cells for the stomach, pancreas and intestine were found to segregate immediately after completion of gastrulation. Transplantation experiments showed...
To determine the origin of the ventral pancreas, a fate map of the ventral pancreas was constructed using DiI crystal or CM-DiI to mark regions of the early chick endoderm: this allowed correlations to be established between specific endoderm sites and the positions of their descendants. First, the region lateral to the 7- to 9-somite level, which has been reported to contribute to the ventral pancreas,...
