Fig. 6: In vivo therapeutic efficacy of photosynthetic system in myocardial ischemia mice.

A Schematic illustration of the animal treatment protocol in the MI model. B ECG of mice before (left) and after (right) induction. C Echocardiography of mice in different treatment groups after treatment for 7 days. D–G Quantitative analysis of the EF, FS, LVESV and LVESD at different periods (n = 6, n represent biologically independent animal samples in each group, mean ± s.d.). H Representative images of the mouse ischemic cardiac detected by Color Doppler Flow Imaging. I TTC staining of hearts from mice in different groups. J Masson trichrome staining displayed the fibrous tissue (blue) and myocardium (red) and HE trichrome staining of sections of hearts from mice in different groups, scale bar: 100 μm. K HIF-1α (red) and DAPI immunostaining (blue) of myocardium in different groups, scale bar: 50 μm. L–N Quantitative analysis of collagen area, fibrosis area, infarct area (n = 6, n represent biologically independent animal samples in each group, mean ± s.d.). Statistical analysis was performed using unpaired two-tailed Student’s t test. Source data are provided as a Source Data file.
