Electrical signaling in bone tissue

Electrical signaling in bone tissue refers to how bones generate and respond to endogenous and exogenous electrical and electromagnetic fields, largely through electroactive material properties (piezoelectricity, dielectric, etc.) and the activation of cell membrane ion channels and signaling cascades. Electrical or electromagnetic stimulation can regulate membrane potential, induce ionic flux (especially calcium), and activate signaling pathways essential for bone cell proliferation, differentiation, and mineralization, notably the Wnt/β-catenin and TGF-β pathways. These processes are central to bone repair, remodeling, and the effectiveness of bone tissue engineering and regenerative therapies. As a concept, "electrical signaling in bone tissue" is not a single molecular target but rather includes a network of molecular mechanisms and electrosensitive elements involved in bone physiology and healing[3][1][2][5]. This entry is not a suitable canonical molecular target, but is an important conceptual therapeutic area.
