Epidermal cell renewal in seborrheic skin of dogs.

Epidermal cell renewal time of seborrheic skin was estimated in 8 adult Cocker Spaniels and 5 adult Irish Setters, using autoradiography after [3H]thymidine was given intradermally. Cell renewal time of the viable epidermis was approximately 7 days. Seemingly, the seborrheic skin observed in these Cocker Spaniels and Irish Setters was associated with an altered rate of epidermal keratinization.
