Cell therapy holds the promise of delivering the next generation of future medical breakthroughs. In this respect, multipotent progenitor cells such as human mesenchymal stem cells (hMSCs) have attracted high clinical interest because of their ability to differentiate into various cell types and their immunoregulatory properties. Furthermore, hMSCs express only low levels of class I major histocompatibility complex (MHC I) molecules on their surfaces and are therefore invisible to a host’s immune system. Finally, hMSCs can actively suppress the innate…
