abnormal pancreatic islet morphology ( J:136131 )

• fewer cells are induced to produce glucagons than in Pdx1^tm1Macd/Pdx1⁺ Tg(tetO-Neurog3)8Ggu mice

endocrine/exocrine glands

abnormal pancreas development ( J:136131 )

• mice exhibit precocious endocrine differentiation, converting 1.8-fold more pancreatic cells to glucagon producing, immature alpha cells at E11.5 than in Pdx1^tm1Macd heterozygotes

• however, this conversion is not sustained later in development as E18.5, only rare glucagons producing cells are found
