Ngn3{T2A.nCre} mouse ESC line A mouse ESC line in which part or all of the targeted gene, Neurogenin 3 (NCBI Gene ID: 11925) is replaced to create Ngn3{T2A.nCre} using the Loxed Cassette Acceptor allele ). In this mouse ES cell line, one of the two bi-partite Cre molecules, nCre, was knocked in upstream of Ngn3 coding sequence by RMCE in Ngn3.HA.LCA ES cell line. nCre sequence is expressed from policistronic mRNA linked by 2a peptide to Ngn3 coding sequence allowing for simultanious expression of both proteins from Ngn3 promoter. This mouse line, in combination with Nkx2.2-cCre mouse line, allows to label pancreatic epithelium cells that co-express high levels of Ngn3 and Nkx2.2 during mouse embryonic development.
