mouse strain Rosa26{(Nepn.Cherry)Mgn} mouse strain A mouse strain in which part or all of the targeted gene, gene trap ROSA 26, Philippe Soriano (NCBI Gene ID: 14910) is replaced to create Rosa26[Nepn.Cherry] using the Loxed Cassette Acceptor allele Rosa26{tm1(LCA)}). Nephrocan (Nepn) has been shown to be expressed specifically during early endoderm development. A Nepn promoter driven reporter (Cherry) has been inserted in the Rosa26LCA locus by recombinase mediated cassette exchange. This mouse line will be useful in visualizing whether Nepn can be used as a specific DE marker for beta-cell development. Person: Mark A.
