Morphological studies on prespermatogonia and pre-Sertoli cells in the testes of 6- to 11-day-old golden hamsters

摘要

The developmental progression of prespermatogenesis in the testes of 6- to 11-day-old golden hamsters has been studied by means of light and electron microscopy. The solid testicular cords prove to be built up by germ and supporting (pre-Sertoli) cells. The germ cells are present as centrally placed T1-prespermatogonia on days 6–7. Subsequently they develop into T2-prespermatogonia, shifting towards a more peripheral position within the testicular cords. From day 10 onwards, most of the germ cells are A-spermatogonia now occupying a marginal position within the cord
