Summary
The mitotic activity of epithelium of the end portions of the mammary glands was studied during various stages of sexual cycle in nonlinear white mice. The rise of mitotic activity corresponds to the maximal effect of estrogenic hormones in time. The mitotic activity is maximal in estrus and proestrus and is equal, on the average, correspondingly to 6.8 and 7.0 mitoses per thousand epithelial cells. In diestrus the mitotic activity is minimal and equals, on the average, 1.2 mitoses per thousand cells.
