Abstract

Oligodendroglia synthesize myelin in the CNS. in vitro, oligodendroglia may be identified by the binding of monoclonal antibodies against galactocerebroside, a myelin-specific galactolipid. Oligodendroglial trophic factor is a protein mitogen for cells of the oligodendroglial lineage. When oligodendroglia in cerebral white matter cultures are treated with oligodendroglial trophic factor, galactocerebroside-positive cells undergo mitosis but fail to express the myelin structural proteins, myelin basic protein and proteolipid protein. Oligodendroglia treated with oligodendroglial trophic factor, however, do express 2′, 3′-cyclic nucleotide 3′-phosphodiesterase and myelin-associated glycoprotein in a manner similar to oligodendroglia treated with platelet-derived growth factor. Oligodendroglial trophic factor, therefore, generates a population of somewhat 'immature' oligodendroglia, which are galactocerebroside, myelin-associated glycoprotein and 2′, 3′-cyclic nucleotide 3′ phosphodiesterase positive but myelin basic protein and proteolipid protein negative.
