This mouse contains a cyan fluorescent protein (CFP, Cerulean), tagged with 3 copies of an SV40 NLS knocked into the endogenous Pdx1 gene.  This mouse strain enables prepancreatic endoderm to be easily identified in the developing mouse embryo and the isolation of Pdx1(+) cells by FACS.

Genetic Alteration

Mutation #1: RMCE Targeted Mutagenesis
Type of AlleleGene Replacement
Targeted GeneName: pancreatic and duodenal homeobox 1
Symbol: Pdx1
NCBI: 18609
Allele Name: targeted mutation 1.2
Symbol: Pdx1tm1.2(CFP)
MGI: MGI:5438568
Description of Targeting Vector

Coding sequences for a nuclear localized Cerulean followed by the beta globin splice/polyA sequence were inserted into exon 1 of the Pdx1 locus.  Using recombinase-mediated cassette exchange (RMCE), the cassette was inserted into the Pdx1LCA. The exchange cassette also contains a flrted (flanked by FRT) pgk-Hygro sequence for positive selection after RMCE.  The pgk-Hygro cassette is removed after germline transmission.

Background Strain Information

Strain Type Inbred Strain
Chimera/Founder Genetic Background 129S6/SvEvTac
Current Genetic Background CD-1
Number of Generations Backcrossed 9
Strain Description

Mice containing the Pdx1CFP allele were bred to FlpE-expressing transgenic mice to remove the hygroR selection cassette.  Animals with this allele are currently being maintained in a CD1 (outbred) genetic background.
