title: [Cholinesterase activity in transplantable tissue cultures].
abstract: Comparative cytochemical investigation was undertaken to study cholinesterase activity in reinactivated cell strains: Hela, RH, in hamster fibroblasts and in mouse ependymoblastoma. In the cells of ependymoblastoma, butyrilcholinesterase was predominantly discovered. Dynamics of the enzyme activity was inversely proportional to the rate of cell division. Its maximal activity was related to the stage of cellular monolayer formation. Acetylcholinesterase activity in the mouse ependymoblastoma culture was not great.
