insulin-like growth factor

Insulin-like growth factor (IGF) is a hormone similar in structure to insulin that plays a key role in growth and development. It is primarily produced by the liver in response to growth hormone and helps promote the growth of bones, muscles, and other tissues. IGF supports cell growth, repair, and survival, contributing to overall physical development from childhood through adulthood. It also helps regulate metabolism and influences various bodily functions. Proper levels of IGF are essential for healthy growth, and imbalances can be linked to growth disorders and certain diseases.
