Establishment of a human oligodendroglial cell line

A human oligodendroglial cell line has been established from a mixed glioma. Over a period of 22 months, the cell consisted of cells with the morphologic features of such a strong perinuclear halo, dichotomous branching, and a tendency to aggregate and float in the medium. In small aggregates, most cells are bipolar. The cell line also continues to synthetize the S-100 protein specific to neural tissue. The response of this cell line to dibutyryl-cyclic AMP is striking, resulting in a remarkable narrowing and elongation of the cell processes. This cell line could be used for studies on glial differentiation and neuron-glia interaction.
