Growth Factors

Meaning

Growth Factors are a diverse group of signaling proteins that act as essential paracrine or autocrine mediators to regulate fundamental cellular processes, including proliferation, differentiation, and survival pathways. These polypeptides bind to specific transmembrane receptors, initiating intracellular cascades that dictate cell fate and tissue remodeling. They are central to tissue repair, development, and maintaining adult homeostasis. Many growth factors exhibit cross-talk with steroid hormone signaling.
