iPSCs‐derived CMs‐loaded conductive microneedles for the treatment of MI. (A) Schematic illustration of iPSCs‐derived CMs‐loaded CNTs‐integrated conductive MN array patch. (B) H&E staining results of sham group, MI group without treatment, MI+cell patch group, MI+cytokine patch group, and MI+cell+cytokine patch group, respectively (scale bar: 500 µm). (C) Quantitative analysis of left ventricular wall thickness. (D,E) LVEFs measured by echocardiography 1 day before surgery (baseline) and 7 days after surgery. ^* p < 0.05 when compared with MI group.
