    TLDR αCT1 improves scar appearance by changing early collagen structure.
    The study investigated the effects of the peptide αCT1 on scar formation, focusing on its impact on collagen matrix structure. In vivo trials with humans, rats, and guinea pigs showed that αCT1 treatment led to increased collagen fiber disorganization and density at early stages, which diminished over time. The guinea pig model closely mirrored human collagen changes, outperforming the rat model. In vitro, αCT1 enhanced procollagen 1 synthesis in murine fibroblasts, suggesting increased collagen production as a mechanism for early density changes. These findings indicated that αCT1 improved long-term scar appearance by altering early collagen matrix organization, providing a foundation for future research on wound healing and scar treatment.
