Direct conversion of pig fibroblasts to chondrocyte-like cells by c-Myc

a The proliferation ability of c-Myc-expressing PEFs (LV-c-Myc), vector-expressing PEFs (LV-con) and pPr Ch was analysed by CCK8 assay. b Colony formation assay for c-Myc-expressing PEFs. c EdU assay for the proliferation ability of c-Myc-expressing PEFs. d Representative histograms for cell-cycle distribution of c-Myc-expressing PEF
