We also succeeded in generating female miniature pig-derived fibroblast cell lines that harbour the DMD+/− genotype composed of wild-type and exon 52-deleted alleles (data not shown), paving the way to generate the carrier miniature sow through SCNT as we previously demonstrated for a pig model of another genetic disease, cystic fibrosis [48]. This evidence concerns the gene DMD and cystic fibrosis.
