摘要
Mesenchymal stromal/stem cells(MSCs) are multipotent cells under consideration as a potential new therapy for a variety of inflammatory diseases including certain neurological disorders. It is generally thought that the efficacy of cell therapy in attenuating damage after ischemia, inflammation, or injury depends on the quantity of transplanted cells recruited to the target tissue. However, only a small number of systematically infused MSCs can effectively migrate to target sites, which significantly decreases the efficacy of exogenous cell-based therapy. In this review, we discuss specific factors influencing MSC migration, and summarize current strategies that effectively promote the motility of MSCs. In addition, we describe several protocols to improve the migration of stromal cells into the nervous system and, therefore,enhance the efficiency of engraftment as means of treating neurological disorders.
