mouse strain Nkx2.2{(Cre-Knock-in)} mouse strain A mouse strain in which part or all of the targeted gene, NK2 transcription factor related, locus 2 (NCBI Gene ID: 18088) is replaced to create Nkx2.2{Cre-knock-in)} using the Loxed Cassette Acceptor allele Nkx2.2{tm1(LCA)}). In this mouse line, one of the two bi-partite Cre molecules, cCre, together with the IRES sequence was knocked into the site directly upstream of the Nkx2.2 start codon using RMCE in the Nkx2.2[LCA] allele. The presence of the IRES sequence allows for transcription of cCre and Nkx2.2 from the native Nkx2.2 locus at the same time. This mouse line allows the labeling of pancreatic epithelium cells that co-express high levels of Ngn3 and Nkx2.2 during mouse embryonic development. Nkx2.2{(Cre-Knock-in)} Person: Mark A.
