Biogenic synthesis of magnetic nanoparticles in human stem cells and their potential applications in regenerative medicine.

Dr. Aurore Van de Walle, Laboratoire Matière et Systèmes Complexes

The natural occurrence of magnetic nanoparticles in a variety of organisms, such as the magnetotactic bacteria and certain birds and mollusks, has largely been demonstrated and their role sometimes explained. Such nanoparticles have also been detected in various human organs, including the brain, heart and liver ; however, in humans, their origin and role remain uncertain. An endogenous provenance had long been suspected but never demonstrated until recently, by us. We indeed observed that, upon internalization of chemically synthesized magnetic nanoparticles in human stem cells, the cells have the ability to degrade these nanoparticles and to synthesize new magnetic nanoparticles from the degradation products. This finding, in addition to bringing a cell model for further understanding of this biosynthesis mechanism, opens up to the possibility of producing 100% biogenic magnetic nanoparticles, which might have advantageous properties for regenerative medicine applications.
