Peripheral Localization of DNA Synthesis in the Seminiferous Epithelium


WHILE using autoradiography to study DNA synthesis and cell cycles of spermatogenesis, we have noted a consistent preferential localization of tritiated thymidine in spermatogonia of the peripheral seminiferous tubules of the testis, and a significantly lower thymidine uptake in the tubules of interior regions.
