[In vivo migration of mesenchymal stem cells]

Mesenchymal stem cells (MSC) have the capacities of low immunogenicity, multiple differentiation, hematopoietic supporting and immunoregulation. And due to their relative ease of availability and ex vivo expansion, the applications of MSC in the prevention and treatment of clinical disease have been rapidly expanded in the recent years. However, increasing investigations indicate that intravenously infused MSC widely distribute to various organs of the recipients. The two intended clinical goals of adoptive cellular therapy reached to the greatest efficiency. Therefore, the ideal candidate cells showed to have the capacity of site-specific relocation in vivo. In this review, the distribution characteristics of infused MSC and the recent research advances on the strategies to enhance targeted migration of MSCs are summarized.
