Cardiac location of PEP(Cy5)–TPP–mitochondria
after
transplantation in IR mice heart. (A) Representative hearts in each
group for the Cy5 location of transplanted mitochondria in the myocardium
at 3 and 6 h (red fluorescence). (B) Representative hearts in each
group for the GFP fluorescent location of transplanted mitochondria
in the myocardium at 24 h (green fluorescence). (C) Statistical analysis
of average radiant efficiency of Cy5 after PEP–TPP–mitochondrial
transfer for 3 and 6 h. (D) Statistical analysis of average radiant
efficiency of GFP after PEP–TPP–mitochondrial transfer
for 24 h. (E) GFP fluorescence imaging of frozen section from IR heart
tissue after PEP–TPP–mitochondrial transfer for 0, 3,
6, and 24 h. Scale bar = 2000 μm. (F) Fluorescent colocalization
imaging of GFP–mitochondria and cTnT–cardiomyocytes
after PEP(Cy5)–TPP–mitochondria transplantation for
24 h. Mean ± SEM, *P < 0.05, **P < 0.01. Statistical analysis was carried out by a one-way ANOVA
analysis followed by Tukey’s test for post hoc analysis.
