In vitro study of bovine oligodendroglia.

Abstract

Oligodendroglia were prepared by 'Ficoll' density gradient centrifugation from the centrum ovale of fetal and adult bovine brains. When cultivated in Rose Chambers, and provided an air bubble was included in the chamber during the cultivation, processes developed on cells around the circumference of the bubble. A sizeable air phase seems to be important for process formation in isolated bovine glial preparations. Various culture systems, media and additions to the cultures were examined for their effect on the behavior of the cultures. Fibroblast overgrowth occurred in oligodendroglial cultures from fetal brains in media supplemented with fetal bovine serum (FBS) but not in medium 199 supplemented with 2.5% FBS.
