How Calcium Powers Wound Healing
Calcium (Ca2+) is not merely a structural component of bones but a dynamic biochemical messenger that orchestrates the intricate processes of wound healing. When a wound disrupts the skin, a rapid surge in intracellular calcium levels acts as the first responder, initiating and coordinating cellular activities crucial for repair. Calcium signals regulate fibroblast activation, immune cell migration, and epithelial cell proliferation, ensuring that each phase of wound healing is seamlessly executed.
