Abstract:Ischemic stroke is one of the main causes of mortality and disability worldwide. However,
efficient therapeutic strategies are still lacking. Stem/progenitor cell-based therapy, with its vigorous
advantages, has emerged as a promising tool for the treatment of ischemic stroke. The mechanisms
involve new neural cells and neuronal circuitry formation, antioxidation, inflammation alleviation,
angiogenesis, and neurogenesis promotion. In the past decades, in-depth studies have
suggested that cell therapy could promote vascular stabilization and decrease blood-brain barrier
(BBB) leakage after ischemic stroke. However, the effects and underlying mechanisms on BBB integrity
induced by the engrafted cells in ischemic stroke have not been reviewed yet. Herein, we
will update the progress in research on the effects of cell therapy on BBB integrity after ischemic
stroke and review the underlying mechanisms. First, we will present an overview of BBB dysfunction
under the ischemic condition and cells engraftment for ischemic treatment. Then, we will summarize
and discuss the current knowledge about the effects and underlying mechanisms of cell therapy
on BBB integrity after ischemic stroke. In particular, we will review the most recent studies in
regard to the relationship between cell therapy and BBB in tissue plasminogen activator (t-PA)-mediated
therapy and diabetic stroke.
