Schematic summarizing mitochondrial function in multiple types of regeneration including cellular, tissue, organ, structure, and whole-body regeneration. Throughout the regeneration process, mitochondria are involved in several pathways including ROS, metabolic reprogramming, mitochondrial morphological dynamics and activity, mitochondrial translocation, and transcriptional regulation. Reactive oxygen species (ROS), cytochrome c (cyt c), oxidative phosphorylation (OXPHOS), adenosine triphosphate (ATP), tricarboxylic acid cycle (TCA), fatty acid oxidation (FAO), mitochondrial membrane potential (Δψm), mitochondrial unfolded protein response (UPRmt), nicotinamide adenine dinucleotide (NAD+)
