[Proliferative processes in the epithelium of the autotransplant and surrounding skin of mice].
Proliferative processes were studied in epithelial cells of skin autografts and the surrounding skin in mice of CBA line. In the animals subjected to the operation but without cortisone injection (Fig. 1, a and Fig. 2, delta), a high proliferative activity in the skin epithelial cells surrounding the autograft was observed during the whole course of the experiment. In the cells of the autograft, the mitotic activity, after inhibition, restored quickly up to the original level, and in 10 days it sharply increased and did not differ from that in the epithelium of the surrounding skin. The amount of DNA-synthesising cells in the epithlium of the autograft at first remained at the original level, and then, after a short sharp rise, it decreased up to its level in the surrounding skin and then was changing nearly in the similar fashion with it. After repeated injection of cortisone both indices of proliferative activity (Fig 1, delta and Fig. 2, delta) in the epithlium of the autograft and of the surrounding skin gradually increased although slower than in the controls.
