Abstract

Recent data show that in humans IGF-1 has insulin-like anabolic and growth promoting effects. However, the plasma levels at which IGF-1 exerts these effects differ. IGF-1 plasma levels similar to those in normal children and adults have a growth promoting effect, but higher levels are necessary for IGF-1 to exert insulin-like anabolic effects, and hypoglycemia is a potential risk. Longitudinal bone growth results from the proliferation and differentiation of chondrocytes in epiphyseal cartilage. We present our data from cultured human epiphyseal chondrocytes, which suggest that epiphyseal cartilage may be a target tissue for IGF-1 action during human fetal and postnatal development.

IGF-1生物作用的人体研究。有证据表明人类胎儿和出生后骺软骨是IGF-1作用的靶组织。
最近的数据显示,在人类中,IGF-1具有类似胰岛素的合成代谢和生长促进作用。然而,血浆中IGF-1发挥这些作用的水平是不同的。血浆中IGF-1水平与正常儿童和成人相似,具有促进生长的作用,但IGF-1必须达到较高水平才能发挥类似胰岛素的合成代谢作用,因此低血糖是一种潜在的风险。纵向骨生长是由骨骺软骨中软骨细胞的增殖和分化引起的。我们展示了培养的人骨骺软骨细胞的数据,这表明骨骺软骨可能是人类胎儿和出生后发育过程中IGF-1作用的靶组织。
