The healing of bone fractures is a tightly regulated process where released growth factors and cytokines interplay within an inflammatory environment in order to reestablish the functional bone. Recent studies have suggested that endothelial cells may dedifferentiate into mesenchymal multipotent cells via a mechanism called endothelial-to-mesenchymal-transition (EndoMT). Transforming growth factor-β (TGF-β) plays a critical role inducing EndoMT. Subsequent differenti...

Destruction of the articular cartilage is the major feature of Osteoarthritis (OA). Ageing is the primary risk factor, but how ageing results in OA is still an enigma. In OA, articular chondrocytes degrade their own matrix, while in healthy articular cartilage they preserve it.Transforming growth factor β (TGFβ) is a central regulator of chondrocyte proliferation, differentiation and extracellular matrix production. Deregulation of TGFβ si...
