N normal phenotype
endocrine/exocrine glands
abnormal pancreas development ( J:125691 )
• the ventral pancreas fails to form at E11.5 with the precursor cells reverting to an intestinal epithelial fate
• growth retardation of the dorsal epithelial bud is evident at E11.5
• the dorsal epithelial bud is significantly smaller at E12.5
• at E17.5, the dorsal pancreatic epithelium is a truncated, poorly branched, duct like structure without islet or acinar tissues
