High-resolution micrograph of muscle staining with MTG demonstrates a significant increase in the mitochondrial mass marker MTG compared to the SHAM group (17.12% ± 20.2 vs. − 8.54 ± 8.41, p = 0.0002). Positive counts are represented by green dots. Greener/brighter images reflect higher counts of MTG stainingBack to article page
