[Surface of the ventral area of the rat third ventricle in the perinatal period].
The correlative scanning and transmission electron microscopy was used to examine the ependyma surface, supraependymal nerve fibers and cells in the ventral region of the 3rd ventricle, during the perinatal period in rats. It has been demonstrated that during the tanycyte differentiation microvilli and blebs of different kinds appear. The distribution of these protrusions reflects the functional specialization of tanycytes in different regions of the infundibular recess. From the 18th day of fetal life, the axons penetrate into the ventricle between the tanycytes to form an extensive network covering the surface of the infundibular recess. Supraependymal cells differ in their shape and ultrastructure, but all of them bear resemblance to macrophages, as they contain numerous lysosomes and phagosome-like bodies.
