FIGURE 6:

Model for the role of BMP and FGF pathways in hepatopancreatic patterning. Bipotential endodermal progenitors, shown in the center of the scheme, can give rise to liver and pancreatic cells through the consecutive action of extrinsic signals secreted from the lateral mesoderm. Hepatic specification is determined by hhex and prox1 expression, whereas pdx1, ptf1a and hlxb9la are markers of pancreatic cell commitment.
