[48] [51] [52] MSC treatment also appears to improve the control of cerebral blood flow and blood–brain barrier permeability, [53] [54] as well as what is currently thought to be the most important mechanism of MSC treatment after stroke, the activation of endogenous neuroprotection and neurorestoration pathways by the release of cytokines ...
