Fibroblasts derived from tissue explants of dilantin-induced gingival hyperplasia and idiopathic gingival fibromatosis show distinct disparity in proliferative responsiveness to epidermal growth factor.

Human gingival fibroblasts derived from tissue explants of two patients with dilantin-induced gingival hyperplasia (DGH) and one patient with idiopathic gingival fibromatosis (GF) were studied with respect to the effect of epidermal growth factor (EGF) on the proliferative characteristics of these cells. Immunohistochemical staining showed that there were… CONTINUE READING
