title: Astroglial proliferation and phenotype are modulated by neuronal plasma membrane.
abstract: The rate of proliferation of rat astroglia cultured in a serum-free medium, estimated by tritiated thymidine radioautography, was diminished by more than 50% by addition of rat central nervous system axolemmal fragments to the culture medium. Addition of the axolemmal fragments also induced a phenotypic alteration of the cultured astroglia, from cells of irregular shape containing a fine meshwork of intracytoplasmic glial fibrils to star-shaped cells with thicker, cable-like glial fibrils.
