[en] Confluent cultured human skin fibroblasts had an extracellular fibrillar matrix of fibronectin and procollagen. Human skin fibroblasts transformed by SV40 did not have such a matrix. Treatment of transformed fibroblasts with 10(-5) to 10(-8) M dexamethasone and 10(-5) to 10(-7) M cortisol, but not testosterone or progesterone, caused partial restoration of the matrix. Glucocorticoid-treated transformed human fibroblasts can serve as a model for partial reversion toward normal or differentiation of transformed human fibroblasts.
