Abstract

The importance of the complex interrelated regulatory pathways involving IGF factors and pancreatic hormones can be observed in several metabolic diseases, where the deregulation of these factors has a wide impact on bone health. These findings have stimulated us to compare the effect of IGF-I, IGF-II, insulin and preptin on human bone cells. The effect on cell differentiation and cell activity of osteoblasts and osteoclasts has been analysed. We have observed a significant effect by IGF-I, a modest effect by IGF-II and preptin and no effect after insulin administration on human primary osteoblast-like cells. All studied factors have shown an induction on human primary osteoclast differentiation and bone resorption activity, with IGF-I being the most potent factor. We hypothesize that these findings may be on the basis of decreased bone mass density observed in several diseases.
