Role of SkQ1 in HCLE cell proliferation. a The indicated concentrations of SkQ1 were mixed with well-separated “single” HCLE cells in maintenance medium and inoculated into six-well plates for 6 days until the MTT reagent was added to terminate the experiments. Photos were recorded at 24, 48 and 144 h post-inoculation. b SkQ1 stimulates HCLE cell proliferation: Results of MTT assays were plotted against the concentrations of SkQ1 used to simulate HCLE cell proliferation
