title: Rat brain microvessel extracellular matrix modulates the phenotype of cultured rat type 1 astroglia.
abstract: Astroglia from immature rat cerebral white matter which were plated on the insoluble extracellular matrix (ECM) secreted by rat cerebral microvessel endothelial cells (RCMEC) and maintained in a defined medium were induced to become stellate and to express glutamine synthetase. These effects were not elicited by RCMEC-conditioned medium. ECM secreted by rat pleural mesothelium elicited a lesser proportion of stellate astroglia and did not induce glutamine synthetase.
