The effect of several endocrine factors on the growth of ventral sebaceous gland of Rhombomys opimus (Rodentia, Mammalia) in diffusion chambers.
The growth of cells of ventral sebaceous gland of Rhombomys opimus was studied in diffusion chambers. The surface properties of these cells and intercellular contacts have been examined in the scanning electron microscope. After 10 to 12 days of cultivation the cells formed aggregates showing a recognizable histological pattern (the ventral sebaceous gland). The pituitary and ovarian gland explants had a significant effect on the differentiation and mitotic activity of epithelial cells of the ventral sebaceous gland. Apparently it is the cell surface itself that alters during the active processes of secretion and differentiation.
