cm prepared from sc3 cells in the absence of testosterone was unable to stimulate the growth of sc3 cells , whereas cm prepared from sc3 cells in the presence of 10 ( -8 ) m testosterone stimulated the growth of sc3 cells in a concentration-dependent manner ( 21 colonies at 10 % and 48 colonies at 20 % ) and this growth-stimulatory effect was not inhibited by 10 ( -6 ) m cyproterone acetate .
