Core Tip

Core Tip: Mesenchymal stromal/stem cells (MSCs) have demonstrated promising therapeutic results in the field of regenerative medicine. However, due to their heterogeneity, the application of MSCs in clinical trials has shown moderate or poor efficacy. Here, we review data on the principal priming approaches for enhancing the therapeutic potential of MSCs. We found that different priming strategies can modify MSC properties and, in this case some therapeutic effects on different disease models can be obtained in relation to dose and/or combination of the priming factors used. The production of priming type-specific functional factors in MSCs could pave the way toward implementing new MSC-based therapies.
