Based on the different properties of cellular adhesions,developmental time\|courses and growth pattern of astroglial cells and oligodendrocytes,a method of isolating glial cells in vitro was developed.The observations under inverted light microscope and scan electronic microscope identified that the morphology of isolated cells were consistent with the previous description.Immumocytochemical examination showed the expressions of markers,the gilal fibrillary acidic protein(GFAP) of astroglia cells and th...
