Characteristics of keratinocytes from the Epfn^−/− epidermis. (A) Expression of various genes characteristic of stem cells, transit amplifying (TA) cells and mature keratinocytes in primary cultures derived from newborn Epfn^+/+ and Epfn^−/− mouse epidermis as measured by microarray analysis. (B) Cell attachment and (C) colony formation assays were performed using primary keratinocytes from newborn Epfn^+/− and Epfn^−/− mice. Data in B show the mean+s.e.m. (four independent experiments); **P<0.01.
