Relation of C-6 glial cells in culture to myelin

C-6 glial cells were shown to contain enriched in their plasma membranes an enzyme, 2':3'-cyclic nucleotide 3'-phosphohydrolase, characteristic of myelin, and, in addition, proteolipid protein and two basic proteins that are identical in their electrophoretic mobilities with the respective proteins found in myelin. The data indicate that C-6 cells exhibit features of myelin-producing glia as well as astrocytes.
