[Ultrastructural and immunohistochemical analysis of cells during the changeover period in isoenzyme synthesis during drosophila ontogenesis].
The ultrastructural and immunohistochemical studies of the differentiating epithelial cells of the ejaculatory bulb in D. littoralis Maigen (=D. imeretensis Sokolov) have shown that the change of synthesis of non-specific isozyme of carboxyl esterase to synthesis of organospecific carboxyl esterase is realized at the same time in all epithelial cells. The epithelium of ejaculatroy bulb is homogeneous by its celluaar composition at all stages of differetiation under study. No mitosing cells or distinct foci of degeneration were found in the epithelial layer after the flight of imago.
