Nanostimulators increase muscle repair capability of stem cells

Muscle ischemia – where the muscles experience damage due to a lack of oxygen – is preferably treated in regenerative medicine with the use of stem cells directly injected into the site to reinvigorate the muscle cells. Muscle ischemia can occur after muscle damage due to injury to a limb, or because of peripheral artery disease. Now, researchers from the University of Illinois (IL, USA) have published a paper in ACS Nano demonstrating the ability of nanoparticles in the form of “nanostimulators” containing a naturally occurring molecule, to encourage stem cells to heal wounds. The paper shows that the nanostimulators...
