    TLDR Thy-1 protein helps improve blood flow and wound healing in the skin.
    The research investigated the role of the GPI-Anchored Protein Thy-1/CD90 in wound healing, focusing on its impact on skin perfusion. The study involved 18 wild type (WT) mice and 20 Thy-1 knockout (Thy-1−/−) mice. Results showed that the absence of Thy-1 delayed wound healing, impaired re-epithelialization, and decreased blood perfusion during the healing process. However, by day 14, wounds closed similarly in both WT and Thy-1−/− mice. The study concluded that Thy-1 enhances wound healing by promoting blood perfusion in the wounded area, making it a potential target for wound therapy.
