Ultrastructural response of epidermis to actinomycin D.
The response of the epidermis to the effects of actinomycin D was analyzed at ultrastructural level. Important cellular alterations were found at 40 h post infectionem. The degree of nucleolar segregation varied depending on the epidermal layer assayed. Analogies and departures between the present findings and previous investigations, on a similar model with X-ray irradiation, are discussed.
