[Differentiation of astroglial cells of the cerebellar cortex in the postnatal development of the rat: a morphological and histochemical study].
The morphological autoradiographic and cytospectrophotometric analysis of proliferation and differentation of the cerebellar cortex astroglial cells has been carried out during the rat early postnatal development. The proliferating astroglial cells constitute a major part of the whole cell population of the internal granular layer during the first week. It was proved by means of double labelling (3H- and 14C-thymidine) that these cells synthesize DNA and divide repeatedly, their division proceeding without preliminary morphological dedifferentiation, i. e. with the preservation of plasmatic processes. A suggestion is put forward that the precursors of the cerebellar cortex astroglial cells under study take their origin from the subependymal zone during the prenatal development. The results obtained allow to identify the proliferating glial cells as the Bergman's glia.
