Abstract
For particularly effective stem cell therapy a nanoparticle is provided. The nanoparticle has a first element consisting of a magnetic material, a support or envelope element consisting of a biodegradable material, a first substance containing an x-ray contrast agent, and a second substance containing stem cells. The stem cells are embodied such that they can be used for angiogenesis or for myogenesis.
