title: The effect of human serum on 3H-thymidine incorporation in human prostate tumors in tissue culture.
abstract: Human prostatic tumors, 4 adenomas and 4 adenocarcinomas, were established in tissue culture. We used the incorporation of 3H-thymidine into deoxyribonucleic acid as a measure of cell activity to compare the effects of supplementing the culture media with human or fetal calf serum. 3H-thymidine incorporation was greater with human serum, with up to 120 per cent increase observed. The addition of dihydrotestosterone (10(-8)M.) did not enhance or inhibit 3H-thymidine incorporation.
