FIG. 3. (A) Representative images of immunocytofluorescence staining showed the cardiogenic MSCs expressed cardiac-specific proteins GATA4 (green) and cTnI (red). Nuclei were stained with DAPI (blue). (B) Treatment of MSCs with differentiation inducer upregulated cardiac marker expressions such as MEF2C, cTnI, and GATA4. MSCs: mesenchymal stem cells, MEF2C: myocyte enhancer factor 2c, cTnI: cardiac troponin I.
