Meeting Agenda/Notes

Using doxycycline-controlled misexpression of a presumed pancreatic commitment transcription factor, Ptf1a, we show that transient Ptf1a expression in the early embryonic mouse endoderm is sufficient to expand the pancreatic gene regulatory network within the posterior foregut.  Upon later differentiation, the entire glandular stomach, anterior duodenum, and much of the extrahepatic biliary system are replaced by pancreatic cell fates.
