External magnetic-field driven delivery of exosomes modulates immune and metabolic changes of dystrophic muscle II

Project description:Exosomes are nanosized extracellular vesicles which have been recently demonstrated as promising agents for tissue repair/regeneration by inducing and guiding appropriate immune responses in dystrophic pathologies. Unfortunately, the accurate manipulation of exosomes by controlling their biodistribution still poses significant challenges. Here we overcome this limitation by developing an externally controlled delivery system for primed ANXA1 myo-exosomes (Exomyo). Effective nanocarriers are realized by immobilizing the Exomyo onto ferromagnetic nanotubes (NT-MAG) to achieve a controlled delivery and localization of Exomyo into skeletal muscles by an applied external magnetic field. Quantitative muscle-level analyses revealed that macrophages dominate the uptake of Exomyo from NT-MAG in vivo, to synergistically promote beneficial muscle responses in a murine animal model of Duchenne Muscular Dystrophy (DMD) thanks to the successful localization of therapeutic Exomyo upon systemic injection. These findings provide valuable insights into the development of exosome-based therapies for muscle diseases and in general highlight the formulation of effective functional nanocarriers aimed at optimizing exosome biodistribution.

Effects of magnetite nanoparticles and static magnetic field on neural differentiation of pluripotent stem cells

Project description:Neural proliferation and differentiation fates of pluripotent stem cells are influenced by external natural forces. Despite the presence of biogenic magnetite nanoparticles in the central nervous system and constant exposure to Earth’s magnetic fields and other sources, there has been scant knowledge regarding the role of electromagnetic stimuli in neurogenesis. Moreover, the emerging application of electrical and magnetic stimulation to treat neurological disorders emphasizes the relevance of understanding the impact and mechanisms behind these stimuli. Here, the effects of magnetic nanoparticles (MNPs) contained in polymeric coatings and the static external magnetic field (EMF, 0.4 Tesla) were investigated on neural induction of murine embryonic stem cells (mESCs) and human induced pluripotent stem cells (hiPSCs) into induced dopaminergic neurons (iDA).
