  • Publication number: 20230121926
    Abstract: Methods are described herein for facilitating tissue regeneration in humans and other large organisms, and kits therefor. Application of an inhibitor of focal adhesion kinase (FAK) to injured tissue may reduce fibrosis and/or scarring during the wound healing process. Patient care for a large number of fibrotic diseases which affect organ function may be ameliorated by such treatment. Kits for application of the FAK inhibitor may include a hydrogel formulation encapsulating the FAK inhibitor.
