Insulin-like growth factor (IGF) is primarily secreted by the liver. It plays a crucial role in growth and development, particularly during childhood, and continues to have anabolic effects in adults. Insulin-like growth factors are part of a complex system that cells use to communicate with their physiological environment. It is influenced by growth hormone (GH), which prompts the liver to produce IGF-I. This factor, in turn, carries out many of the growth-promoting effects attributed to growth hormone.
