The Atf4 KO mice show pancreatic hypotrophy. As early as P4, Atf4 KO mice show fewer and smaller acinar cells in the exocrine pancreas (A, P4 wild-type; B, P4 Atf4 KO, 400x). The arrows point to tubular structures. By three months of age, the majority of the exocrine pancreas is replaced by adipocytes (C, Atf4 KO).
