IGF-1 is one of a number of Insulin-like growth factors. Insulin-Like Growth Factors are produced by many different tissues and have local paracrine and autocrine effects. (see [[Hormones - Anatomy & Physiology|hormones]] for further details). They bind to carrier proteins to extend their half life in the blood. The '''liver''' is the main source of IGF-1.

Hormones that directly stimulate Insulin-like growth factor-I (IGF-I) include growth hormone, insulin and oestradiol.Growth hormone is the main regulator of IGF-I production in the liver and insulin and oestradiol are stimulatory in other tissues.
