Addition of serum to quiescent mouse fibroblasts induces a series of macromolecular changes (a pleiotypic response) followed by DNA synthesis and cell division. A new pituitary hormone, fibroblast growth factor, and hydrocortisone acting at physiological concentrations can completely replace exogenously added serum for the induction of these events in lines of BALB/c 3T3 cells. The induction of cell growth is specific for cultured fibroblasts; no stimulation is observed for mouse epithelial cells or virally transformed fibroblasts.
向静止的小鼠成纤维细胞中添加血清会引发一系列大分子变化(一种多效性反应),随后是DNA合成和细胞分裂。一种新的垂体激素、成纤维细胞生长因子以及生理浓度的氢化可的松,能够完全替代外源添加的血清,从而在BALB/c 3T3细胞系中诱导这些事件。细胞生长的诱导对于培养的成纤维细胞具有特异性;在小鼠上皮细胞或病毒转化的成纤维细胞中未观察到刺激作用。
