Abstract
Insulin-like growth factors (IGFs) are potent mitogens in mammalian cells (Zapfet al., 1981). The mode of action of IGFs has been extensively studied in Balb/c 3T3 cells. Thus, IGFs promote cell cycle progression specifically in competent Balb/c 3T3 cells while IGFs have essentially no effect in Go-arrested cells (Pledgeret al., 1977; Stileset al., 1979). To promote cell cycle progression, IGFs should be exposed to competent cells continuously throughout the Giphase (Pledgeret al., 1977). Hence, it is presumed that IGFs may generate a continuous mitogenic signal. This observation together with the fact that extracellular calcium is required for cell cycle progression have led to the consideration that calcium influx may be a mitogenic signal of IGFs.
