自从1978年获得纯化的胰岛素样生长因子以来,多项研究发现胰岛素样生长因子对细胞和组织的作用,证实胰岛素样生长因子不只局限于有丝分裂刺激作用,也能诱导分化或促进分化功能的表达,而且能根据细胞发育的状态及其他生长因子的调控发挥不同的生物学效应。胰岛素样生长因子1是胰岛素样生长因子家族中的一种低分子多肽。实验发现多种心肌、血管平滑肌等组织细 Since the purification of insulin-like growth factor in 1978, many studies have found that insulin-like growth factor on cells and tissues, confirmed that insulin-like growth factor is not limited to mitotic stimulation, but also induce differentiation or promote differentiation of expression, But also according to the state of cell development and regulation of other growth factors play different biological effects. Insulin-like growth factor 1 is a low-molecular polypeptide in the insulin-like growth factor family. Experiments found that a variety of myocardium, vascular smooth muscle and other fine tissue
