Abstrac: Ischemic stroke (IS) is a life-threatening condition that constitutes the second leading cause of death globally. Despite its high impact on public health, there is a shortage of treatments due to the complexity of the cellular and molecular mechanisms implicated. One main limiting factor for successful IS therapeutic intervention is stroke-induced blood–brain barrier (BBB) damage, particularly over tight junction proteins (TJs). BBB disruption is a well-established feature of IS, accelerating ischemic tissue damage and worsening prognosis. In recent years, mesenchymal stem cells (MSCs) and their small extracellular vesicles (MSCs-sEVs) have emerged as promising therapeutic interventions for several neurological disorders, including IS. However, its efects on BBB repair after IS are not completely understood. In this review, we will discuss novel experimental evidence of MSCs-sEVs efects in BBB protection and highlight the relevance of molecules reported in MSCs-sEVs, their potential cellular and molecular targets, and putative mechanisms implicated in BBB repair, providing a promising research avenue that may translate into efective therapeutic strategies for IS.
