[Morphometric research on the germ and Sertoli cells in prespermatogenesis].

The author investigated the changes in the morphology of germinative and Sertoli's cells during prespermatogenesis of the rat. This problems were studied by morphometric investigations in 20 rats of Wistar strain, divided into age groups: newborns, 5, 10 and 15 postnatal days. The morphofunctional characteristic of these two types of cellular populations in immature rats showed existence of parallelism in the proliferation of these cells, the level of organization and interrelationships between them, which was of substantial significance for creation and further maintenance of an optimal microenvironment, needed for differentiation of sex cells.
