## Abstract When the tumor promoter, 12‐0‐tetradecanoyl‐phorbol‐13‐acetate (TPA), was added to freshly seeded cultures of human diploid fibroblasts, cell growth was inhibited for 24–48 h and then proceeded at the same rate as in controls. After the control cultures had become confluent, cell divisi

## Abstract Stimulation of Balb/c‐3T3 cell growth by TPA requires factors found in serum. We examined the interaction between TPA and serum growth factors in the stimulation of cell growth. The number of cells synthesizing DNA (incorporating ^3^H‐thymidine) within 24 to 30 hours after the addition
## Effect of tumor promoter 12-0-tetradecanoyl-phorboll3-acetate on CD 7 expression by T lineage cells* Phorbol esters exert diverse effects on cellular activation and differentiation. CD 7, a differentiation antigen appearing early in T cell ontogeny, may be involved in the activation and differe

## Abstract The induction of sister chromatid exchanges (SCE) by the tumour promoter 12‐O‐tetradecanoyl‐phorbol‐13‐acetate (TPA) has been studied in V79 Chinese hamster cells comparing control untreated cells with either UV‐irradiated or MNNG‐treated cells. In untreated cells TPA induced SCE at a v
## Abstract The phorbol esters phorbol 12‐retinoate 13‐acetate (RPA) and 12‐O‐tetradecanoyl phorbol 13‐acetate (TPA) were used to investigate the role of tumor promoters in the control of hormone response in normal and leukemic myeloid celts. RPA and TPA inhibited the binding of [20‐3H]phorbol 12,1
