Multipotent mesenchymal stromal cells(MSCs)are actively involved in reparation and inflammation processes,providing damaged tissue reparation and suppressing immune cell responses in *** effects are mostly due to the production of a wide range of paracrine factors,including growth factors and immunomodulatory *** induce immunosuppressive activity,MSCs are primed by inflammatory cytokines,which results in an increased production of immunomodulatory ***,stimulation of reparative properties is also *** viewpoint manuscript highlights the possibilities of inflammatory priming to increase the production of growth factors by MSCs.
