Fig. S4
Liver vs. Pancreas Specification of Mouse Bipotential Endoderm Progenitors is Influenced by PGE2 (Related to Figure 4) (A) Mouse bipotential endodermal progenitors are derived from mouse embryonic stem cells by a step-wise differentiation protocol as shown. (B) Bipotential liver-pancreas endodermal progenitors are detected by triple co-staining for the hepatopancreatic markers Prox1 (green) and Onecut1 (red) as well as the pan-endoderm marker Foxa2 (blue). (C) Bipotential endodermal progenitors exposed to optimal pancreas conditions will be specified into a predominantly Pdx1+ population, whereas progenitors exposed to optimal liver conditions will be specified into a predominantly Hnf4α+ population. Scale bar = 100 µm.
