WebNov 3, 2007 · Pdx1 and Ptf1a are expressed in pancreatic progenitor cells, which give rise to all three types of pancreatic tissue. In addition, Ptf1a has been shown to bind the mammalian Suppressor of Hairless (RBP-J) within the PTF1 complex. Furthermore, loss-of-function approaches have revealed that all three factors are essential for early pancreas ... WebPtf1a and Pdx1 are critical transcription factors of early pancreatic development, as shown by loss of function studies where lack of each gene alone causes almost complete …
