        Scientists uncover how

        a molecule improves

        appearance of surgery scars

        Researchers find clues about how molecule improves appearance of scars

                In a new study, Fralin Biomedical Research Institute at VTC scientists discovered that the alphaCT1 molecule may help repair
                the skin’s collagen matrix. Microscopic imaging of 29-day scar biopsies from the same patient reveals the molecule’s effects
                on collagen organization. Collagen bundles in the untreated scar, right, are more aligned compared to the alphaCT1-treated
                tissue’s collagen, which is more randomly arranged in swirls that resemble unwounded skin. (Gourdie Lab / Virginia Tech)
