Proliferation of epithelial cells of vas deferens and epididymis in young adult rabbits.

Epithelial proliferation of the vas deferens and epididymis was studied in rabbits after flash or continuous labeling with DNA precursor by autoradiography. A high proliferative capacity of the epithelium was found: after 2 days of labeling, 11% of labeled cells were found in the vas deferens and 20% in the ductus epididymidis.
