Primary rat vascular smooth muscle cells cultured on fibronectin in the absence of serum lost smooth-muscle-specific myosin heavy chain but did not enter the cell cycle and proliferate until they were stimulated by serum. Under these conditions accumulation of Id mRNA occurred only in response to serum and was maximal during the G1 phase of the cycle.
在无血清条件下于纤连蛋白上培养的原代大鼠血管平滑肌细胞失去了平滑肌特异性肌球蛋白重链,但在受到血清刺激之前不会进入细胞周期并增殖。在这些条件下,Id mRNA的积累仅在对血清作出反应时发生,并且在细胞周期的G1期达到最大值。
