Due to the wide range of molecules they enclose and their cell type specific assembly, these small membrane vesicles get more and more in the focus of diagnosis, drug delivery and clinical applications. Some preliminary pre-clinical and clinical application of MSC-derived exosomes of scientists at the University Duisburg-Essen revealed very promising results (see below). However, coupled with the fact that beneficial effects of MSC administration are controversially discussed, it appears very likely that not all MSC-derived exosome fractions will exert beneficial effects.
To select for MSC exosomes being able to efficiently suppress inflammation associated symptoms the scientists compared immune modulating activities of independent MSC-derived exosome preparations.
Aiming to treat a 22-years female patient suffering from severe therapy-refractory cutaneous and intestinal Graft-versus-Host Disease (GvHD) grade IV with MSC-derived exosomes, the scientists administered exosomes which revealed the strongest immune-suppressive effects in vitro. The documentation of the impacts on the clinical symptoms and the immune response showed that the selected MSC exosome preparation helped to suppress GvHD symptoms in vivo.
Since the in vivo administration appears to be safe, MSC exosome administration of selected preparations turned out to be a promising new treatment option in the prevention and therapy of diseases associated with acute inflammatory processes, such as GvHD, stroke, heart-attack and neonatal damages of the brain and lungs.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
