    Mechanism of Action<\/h2>\n
    [IMAGE: TB-500 mechanism diagram \u2014 actin polymerization, cell migration, angiogenesis pathways]<\/div>\n
      \n
    • [TODO]<\/span> Actin regulation \u2014 sequesters G-actin, promotes cell migration and cytoskeletal reorganization<\/li>\n
    • [TODO]<\/span> Angiogenesis \u2014 robust new blood vessel formation, VEGF-independent pathway<\/li>\n
    • [TODO]<\/span> Anti-inflammatory \u2014 downregulates inflammatory cytokines, NF-\u03baB modulation<\/li>\n
    • [TODO]<\/span> Stem cell mobilization \u2014 promotes differentiation and migration to injury sites<\/li>\n
    • [TODO]<\/span> Anti-fibrotic \u2014 reduces scar formation, promotes functional tissue repair<\/li>\n<\/ul>\n

      Research Highlights<\/h2>\n
        \n
      • [TODO]<\/span> Cardiac \u2014 post-MI cardiac repair, cardiomyocyte survival (mouse models)<\/li>\n
