Cultured microvascular endothelial cells, astrocytes, pericytes and glioma cells from brain were used in this study. Proliferation of endothelial cells was stimulated by type 1 collagen and moderate hypoxia. Conditioned media from glioma cells failed to fascilitate the growth of endothelial cells. Differentiation of endothelial cells, demonstrated by the formation of capillatry-like structure was stimulated the existence of type 1 collagen. Glioma cells also stimulated the formation of capillary-like structures. Astrocytes migrated and attached to the capillary-like structures, and the formation of blood-brain barrier, proved by the induction of tight junction was observed 9 days after the attactment. Pericytes also migrated and attached to the capillary-like structures.}, pages = {197--202}, title = {1) 脳における血管新生のメカニズムに関する検討 : 培養細胞(内皮, 腫瘍, アストロサイト等)を利用したアプローチ(シンポジウム 血管細胞生物学の進歩, 第517回新潟医学会)}, volume = {110}, year = {1996} }
