A major issue in the clinic is excessive, or hypertrophic, scarring of the skin after injury. Geoffrey Gurtner and his colleagues have now shown that mechanical forces during such injury upregulates focal adhesion kinase (FAK), which in turn leads to the release of a cytokine that promotes inflammation and fibrosis. They also show that genetic deletion of FAK or its pharmacological inhibition results in minimal scarring in a mouse model.
