The basic helix-loop-helix transcription factor Neurogenin3 (Ngn3/Neurog3) is expressed in endocrine progenitor cells in the embryonic mouse pancreas. Ngn3 controls endocrine cell fate decisions. Ngn3 deficient mice do not develop any pancreatic endocrine cells, including insulin producing beta cells, and die postnatally from diabetes. Therefore, the characterization of gene expression in Ngn3-expressing cells and their progeny is of particular interest for the development of novel strategies for cell replacement therapies in type-1 diabetes. Here we describe two studies. In the first study (8 assays) we used mice where the EYFP (Enhanced Yellow fluorescent Protein) is expressed under the control of Ngn3 regulatory elements (knock add on strategy). EYFP-positive, Ngn3-expressing cells, were FACS sorted from embryonic pancreas at day 15.5 (E15.5), as well as EYFP-negative cells. In the second study (6 assays) we compared wild-type and Ngn3 mutant pancreas at E15.5. All samples were hybridized to Affymetrix GeneChip Mouse Genome 430.2.0 array.
