Transforming Growth Factor Beta (TGF-β) is a multifunctional cytokine that plays crucial roles in cellular processes such as cell growth, differentiation, apoptosis, and homeostasis. It belongs to a larger family of TGF-β proteins, which are essential in regulating the immune system and maintaining tissue architecture. TGF-β is secreted by many cell types and exists in a latent form until activated by various mechanisms.
