Fig. 3From: Murine skin-derived multipotent papillary dermal fibroblast progenitors show germline potential in vitroEGF promotes proliferation and formation of large pDFPs spheres (colonies) in vitro. A IF staining of EGFR in epidermal cells, hair follicles and dermal fibroblasts of the skin of E16.5 fetuses and 0 dpp pups; dotted lines indicate dermal and epidermal interface, and black arrows indicate papillary dermis. Pictures were taken using an optical microscope (20x, Olympus BX51, Japan). Scale bars, 100 μm. B Effects of EGF on the diameter of P2 pDFP colonies.
