    Strain Description

    Phenotype
    In pluripotent stem cells (ESCs and iPSCs) derived from this mouse strain on the 129 background, no loss of Dlk1 genomic imprinting by DNA hypermethylation resulting in bi-allelic reporter expression occurs. Such loss of imprinting is seen in animals on the B6J background (see strain 71306) allowing mapping of genetic variants controlling epigenetic stability.

    Strain Development
    To generate targeting vectors for insertion of reporter genes into the 3’ UTR of Dlk1, a 6.7kb EcoRV fragment was isolated from BAC RP23-117C15 and cloned into pBluescript together with a floxed PGK-neoR cassette. In the resulting pBS-Dlk1, a SnaBI site was introduced at the site corresponding to position chr12:109,460,514 in mm10 using site-directed mutagenesis (Agilent QuikChange II). This site was used to insert the coding sequence of IRES-Venus or IRES-Tomato. V6.5 ESCs were electroporated with linearized (by SacII digestion) targeting vectors, followed by selection in G418-containing media. Correctly targeted clones were identified by Southern blotting of AseI-digested genomic DNA, using a 770bp HincII/AseI fragment probe isolated from pBS-Dlk1. Following confirmation, the PGK-neoR cassette was removed by transient transduction with Adeno-Cre. Resultant ESCs were injected into diploid blastocysts and transgenic chimeric mice bred with 129 animals to establish homozygous Dlk1 reporter mouse strains.
