MiR-21-5p-enriched exosomes from hiPSC-derived cardiomyocytes exhibit superior cardiac repair efficacy compared to hiPSC-derived exosomes in a murine MI model

Figure 8 Effects of exosomes applied to AC16 cells on the expression level of microRNA 21. A: AC16 cells absorb human-induced pluripotent stem cell-exosomes (hiPSC-exos). Scale bar = 75 μm; B: AC16 cells absorb hiPSC-cardiomyocyte (CM)-exos Scale bar = 75 μm; C: Expression of miR-21 in AC16 cells after absorption of iPSC-exos; D: Expression of microRNA 21 in AC16 cells after absorption of hiPSC-CM-exos, ^bP < 0.01.
