✦ Synopsis

Adaptation of monolayer cultures of a clonal line of rat glial cells to suspension culture resulted in the nearly complete loss of certain surface antigens. This change in surface antigenicity was paralleled by the loss of the ability of the cells to accumulate in vitro a protein specific to the nervous system ("S100-protein"). In contrast, when glial cells were co-cultivated in monolayer culture with another cell line apparently lacking these surface antigens, the number of these antigens was markedly increased. The possibility of a causal relationship between the changes in the surface antigenicity and the expression of differentiated function is considered.
