title: [Acetylcholinesterase activity of neuroblastoma and different glial cells in co-culture].
abstract: When mouse neuroblasts (clonal line M 1) and hamster astroblasts (clonal line NN) were co-cultured, the originally low activity of acetylcholinesterase of both lines was drastically increased. After 2 months the neuroblastoma M 1 cells were reisolated from the co-culture and were found to contain 10 times higher activity of acetylcholinesterase than the original M 1 cells. This increased activity was maintained over more than 14 subcultures. In contrast, co-cultivation of neuroblastoma M 1 cells with rat astrocytoma cells (clonal line C 6) resulted in a decrease of actylcholinesterase activity compared to either original cell line.
