Insulin-Like Growth Factor 1

Meaning

Insulin-Like Growth Factor 1 (IGF-1) is a polypeptide hormone structurally similar to insulin, playing a critical role in mediating the effects of Growth Hormone (GH). Primarily produced in the liver, IGF-1 is essential for promoting cell growth, proliferation, and differentiation in nearly all tissues. Clinically, it serves as a key biomarker for assessing GH status and anabolic function.
