Transforming growth factor β1 (TGFβ1) is a multifunctional cytokine known to be involved in a number of human diseases. It is believed to play an important role in wound healing and repair, as it is a key regulator of the production and remodelling of the extracellular matrix through its effect on mesenchymal cells. Over the last few years, it has become evident that the signalling pathway of TGFβ is complex with numerous receptor–ligand interactions, intracellular pathways and a number of mechanisms, which not only control the signalling but may also decide the response to the TGFβ signal. This review focuses on TGFβ1 signalling and the role that TGFβ1 plays in wound healing, repair and scarring.
