microcurrent triggers calcium signaling that drives fibroblast growth and movement
Chelation of intracellular Ca²⁺ with BAPTA-AM significantly attenuated the pro-proliferative and pro-migratory effects of microcurrent stimulation in NIH/3T3 fibroblasts, confirming calcium signaling as a required mediator.
What this means for you
Fibroblasts are the cells that build collagen and close wounds. When microcurrent activates calcium signaling inside them, they multiply and migrate more actively — the two things your body needs to repair tissue, firm skin, and recover from injury. This finding confirms the mechanism isn't coincidental; calcium is the required switch.
