Insulin-Like Growth Factor (IGF) is a protein that plays a crucial role in growth and development. It is primarily produced in the liver and is stimulated by Growth Hormone. IGF helps promote cell growth, division, and survival, making it essential for normal physical development during childhood and adolescence. In addition to its role in growth, IGF is involved in various metabolic processes, including the regulation of glucose and fat metabolism. Abnormal levels of IGF can be linked to health issues, such as diabetes and certain types of cancer, highlighting its importance in maintaining overall health.
