Establishment and characteristics of three mouse cell lines from embryos of different inbred strains.
Three cell lines were established from embryos of DDD, AKR, and C3H mouse strains based on "3T3" transfer schedule. These cell lines were designated as Y-DD, Y-AK, and Y-CH, Y-DD and Y-CH showed a gradually increasing growth rate during the course of their establishment, whereas Y-ak indicated a constant growth rate, a low level of saturation density, and a tetraploid range of chromosome mode. In transformation experiment, control cultures of Y-DD and Y-CH already lost a density-dependent inhibition, but Y-AK was found to be very sensitive to density-dependent inhibition. Y-AK showed a higher activity in benzo[a]pyrene metabolism (4100 pmol/10(6) cells/24 hr) than Y-DD and Y-CH (700 and 2600 pmol/10(6) cells/24 hr).
