摘要

The ultrastructure of the mid-intestine of four sturgeon species and their hybrids was studied. Apart from enterocytes and glandular goblet cells, the cells with microvilli, endocrine cells, and immuno-competent elements were revealed. Specific cells responsible for the primary immune response, analogous to mammalian A/-cells, were discovered in sturgeon fishes. The ultrastructural characteristics common for the mid-intestinal epithelium of all the sturgeon fishes studied were determined. Species-specific features of intestinal epithelium of the parent species, which were characteristic of the hybrids, were revealed.
