The quality of mouse embryonic fibroblasts (MEFs) is dictated by the right strain of mouse such as CF-1. Pluripotency-supportive MEFs and conditioned media (CM) obtained from these should contain optimal concentrations of Activin A, Gremlin and Tgfβ1 needed for the Activin/Nodal and FGF pathways to co-operatively maintain self-renewal and pluripotency.
