Here, we demonstrated chimeric adeno-associated virus (chimeric AAV), AAV-DJ-mediated cardiovascular reprogramming strategy to generate new cardiomyocytes and limit collagen deposition in cardiac fibroblasts by inducing synergism of chimeric AAV-expressing Gata4, Mef2c, Tbx5 (AAV-GMT)-mediated heart reprogramming and chimeric AAV-expressing thymosin β4 (AAV-Tβ4)-mediated heart regeneration. AAV-GMT promoted a gradual increase in expression of cardiac-specific genes, including Actc1, Gja1, Myh6, Ryr2, and cTnT, with a gradual decrease in expression of a fibrosis-specific gene, procollagen type I and here AAV-Tβ4 help to induce GMT expression, providing a chimeric AAV-mediated therapeutic cell reprogramming strategy for ischemic heart diseases.
