This study uses in vivo 2-photon imaging and photoactivatable fluorescent labeling to show that mitochondrial dynamics in skeletal muscle are slower in vivo than previously thought, with age-related differences and exercise-induced increases.

This study shows Fis1 depletion reduces dendritic mitochondrial length and alters mitochondrial function, leading to increased calcium levels and changes in dendritic branching and spine density.
