A model illustrating the role of mitochondrial fragmentation and reactive oxygen species (ROS) signaling in wound repair highlights the various functions of mitochondria in both single-cell closure and multicellular healing. When tissue is wounded, there is a rapid increase in cytosolic calcium (Ca²⁺) due to external influx or internal release, which triggers mitochondrial fragmentation through the actions of DRP-1 or MIRO-1. In response to this calcium increase, fragmented mitochondria enhance the production of mtROS, aiding in the closure of the actin ring in single-cell systems. Additionally, mtROS may support multicellular wound healing by participating in processes such as angiogenesis and inflammation [42].
