title: Growth requirements in vitro of oligodendrocyte cell lines and neonatal rat brain oligodendrocytes.
abstract: I have defined the basic requirements for the proliferation of cell lines expressing oligodendrocyte properties and for the survival of galactocerebroside-positive oligodendrocytes derived from neonatal rat brains. Conventional serum-containing medium can be replaced by 01 medium, a chemically defined medium supplemented with insulin, transferrin, sodium selenite, and biotin. Thyroid hormone is not required. When cells are plated directly into O1 medium, the substratum has to be modified by precoating with polylysine and adding fibronectin to the medium prior to the cells. Both cell lines and brain cells can be subcultured numerous times in O1 medium without initial culture in serum-containing medium. Brain cultures can be maintained in O1 medium for several months and contain a significantly higher percentage of mature oligodendrocytes, a lower number of astrocytes, and no fibroblasts as compared to cells maintained in serum-containing medium.
