[Ultrastructure of epithelial cells of rat seminal vesicles in the period of functional transformation and puberty].

It was found that the ultrastructure of the epithelial cells of the rat seminal vesicles changes during the period of puberty. The changes consist in formation of the cell organelles that participate in the production of secretion and in differentiation of the epithelial cells into the secretory and basal cells. The complementary biochemical studies indicate the close relationship between the formation of the typical ultrastructure of the secretory glandular cells of seminal vesicles and the presence of fructose in the secretion of these glandular cells.
