[Formation of S-100 containing cells of the hypothalamus and adenohypophysis in normal ontogenesis and in protein deficiency].
By means of the indirect immunohistochemical method distribution of S-100 containing cells has been studied in sections of the mediobasal hypothalamus (astrocytes) and adenohypophysis (follicular-stellate cells) in newborn, 10- and 21-day-old rats under normal development and under protein insufficiency. For this the animals are given the diet containing 6% of protein (control--25% of protein). S-100 containing cells are revealed in the hypothalamus and adenohypophysis in 10- and 21-day-old animals. In the brain of the newborn rats S-100 immunoreactive cells are not revealed. At the ultrastructural level the diaminobenzidine (DAB) reaction products in the immunoreactive cells are revealed diffusely along the whole cytoplasm of the cells, in nuclei the DAB reaction products are absent. Part of S-100 containing cells is essentially lowered, comparing with the control. In the rat adenohypophysis part of S-100 containing cells from the 10th up to the 21st day also decreases. Unlike the hypothalamus, however, content of cells, immunopositive to S-100 exceeds the analogous index in the control rats of the corresponding age groups.
