As the vast majority of studies focused on the effects of MSCs for photon irradiation-induced toxicities, little is known about the regenerative abilities of MSCs for particle irradiation-induced tissue damage or the effects of particle irradiation on the stem cell characteristics of MSCs themselves. MSC-based therapies may help treat particle irradiation-related tissue lesions in the context of cancer radiotherapy. As the number of clinical proton therapy centers is increasing, there is a need to decidedly investigate MSC-based treatments for particle irradiation-induced sequelae. Furthermore, therapies with MSCs or MSC-derived exosomes may also become a useful tool for manned space exploration or after radiation accidents and nuclear terrorism. However, such treatments require an in-depth knowledge about the effects of particle radiation on MSCs and the effects of MSCs on particle radiation-injured tissues. Here, the existing body of evidence regarding the particle radiobiology of MSCs as well as regarding MSC-based treatments for some typical particle irradiation-induced toxicities is presented and critically discussed. %K mesenchymal stem cells (Other) %K mesenchymal stromal cells (Other) %K normal tissue toxicities (Other) %K particle irradiation (Other) %K radiation accidents (Other) %K radiotherapy (Other) %K space irradiation (Other) %K stem cell therapy (Other) %F PUB:(DE-HGF)16 %9 Journal Article %$ pmid:33912447 %2 pmc:PMC8071947 %R 10.3389/fonc.2021.616831 %U https://inrepo02.dkfz.de/record/168555
