Exosomes Derived from TIMP2-Modified Human Umbilical Cord Mesenchymal Stem Cells Enhance the Repair Effect in Rat Model with Myocardial Infarction Possibly by the Akt/Sfrp2 Pathway

<div>huc-exo<sup>TIMP2</sup> inhibited cardiac fibroblast proliferation and MMP2/MMP9 production. (a) Cardiac fibroblast proliferation rate measured at 0, 24, 36, and 48 hrs with the CCK8 assay. OD540: optical density at 540 nm. (b) Immunoblots and (c) immunofluorescence showing the expression levels of <i>α</i>-SMA in cardiac fibroblasts and comparison of quantified levels. (d, e) Expression levels of MMP2 and MMP9 mRNAs and proteins in the cardiac fibroblasts across different groups. Control: untreated; TGF<i>β</i>: treated with TGF<i>β</i> alone; NC: treated with huc-exo<sup>NC</sup> following TGF<i>β</i>; TIMP2: treated with huc-exo<sup>TIMP2</sup> following TGF<i>β</i>. <span
