Abstract

Featured Application: The results highlighted the role of low-intensity electromagnetic fields in fish bone regeneration. Such a simple in vivo model can be used to elucidate the responsiveness of skeletal tissue to specific physical forces useful to design new therapeutic approach in human bone diseases. Low-Intensity electromagnetic fields (LI-PEMFs) are known to induce a trophic stimulus on bone tissue and therefore have been largely used for the treatment of several musculoskeletal disorders. High intensity (HI) PEMFs add interesting features to bio-stimulation such as electroporation, a phenomenon characterized by transient increased cell permeabilization to molecules, and diamagnetism, a water-repulsive effect based on the diamagnetic properties of water and transmembrane ions gradients. Despite the rapid evolution of technology, the biological mechanisms underlying it are still poorly understood. In order to evaluate the effectiveness of this particular stimulation, HI LF-PEMFs were used to stimulate the caudal fin rays of adult zebrafish. Actually, the zebrafish fin regeneration is a simple, well understood, and widely adopted model for studying bone regeneration. A controlled amputation fin experiment was then conducted. Regenerated bone matrix of fin rays was dyed with calcein and then analysed under fluorescence microscopy. Both the length and the area of regenerated fin’s rays treated with HI LF-PEMFs resulted significantly increased when compared with non-treated.
