In this study, we regenerated skin and its appendages by transplanting cultured normal dermal fibroblasts, into which morphogen genes had been introduced. We cultured normal dermal fibroblasts obtained from Fisher 344 rats on the surface of hydroxyapatite beads, and then adsorbed them onto the surface of a collagen sponge, which was transplanted into a full‐thickness skin defect prepared on the backs of rats. Before transplantation, genes were introduced into the dermal fibroblasts via adenovirus vector (ad)‐bone morphogenetic protein 2 and ad‐wingless int 3 genes in addition to fibroblast growth factor‐2 protein. By Week 4, the appearance of follicle germs or primitive hair germs was observed only in the ad‐bone morphogenetic protein 2+ad‐wingless int 3 combined with the fibroblast growth factor‐2 protein group. By Week 16, in that same group, hair follicles having mature pilosebaceous systems with equally spaced localization had formed in the ulcer wound.
