First, transduction efficiency and transgene expression quality were determined in Ad.MyoD-infected mesenchymal stem cells isolated from fat (adipose mesenchymal stem cells, hADMSC) and dental tissues (dental follicle stem cells, hDFSC) of donors and in primary skin fibroblast (hFB) at different multiplicities of infection (MOIs). Here, MYOD1 is linked to infection.
