title: [The effect of liposomes containing cholesterol or 7-ketocholesterol on the capacity of cultured cells to form colonies].
abstract: The experiments with the cultivated Chinese hamster cells showed that the incubation of cells with (phosphatidylcholine+cholesterol+7-keto-cholesterol)--containing liposomes (4:3:1 by weight) during two hours leads to a decrease in the effectiveness of colony-forming up to zero, while the (phosphatidylcholine+cholesterol-containing liposomes (1:1 by weight) reduce the effectiveness by 90%. Furthermore, the cholesterol-containing liposomes cause the decrease of the number of colonies with maximal size, accompanied by the increase of the number of colonies with middle size.
