co-cultivation of ccrf-sb-t1 and bs b-lcls also resulted in a significant reduction in sce level , from 70 to 35 , in bs cells , lowered the brdu concentrations necessary for sister-chromatid differential staining ( scd ) from 15 micrograms/ml ( 0.05 mm ) to 2.0 micrograms/ml ( 0.01 mm ) and resulted in a completely normal level of sce in ccrf-sb-t1 cells .
