Ransforming growth factor beta TGF-β is a potent growth suppressor of normal epithelial cells. However, many types of invasive cancer cells (e.g. breast cancer frequently overproduce TGF-β to enhance their growth and metastasis. Quite frequently, these cells do not possess a functional type II TGF-β receptor, indicating an aberrant TGF-β signaling is responsible for promoting cell growth.

Transforming growth factor beta 对於正常的上皮细胞是一个很强的生长抑制因子，然而，许多种具有蔓延侵犯性的癌细胞常常是表现大量的 TGF-β来促进细胞生长与转移，这些癌细胞通常不表现具有功能性的第二型 TGF-β receptor，显示有另类的 TGF-β讯息传递可以促进细胞生长。
