PLAT and Stroke: While the introduction of tissue plasminogen activator (tPA)‐mediated thrombolysis and endovascular thrombectomy has greatly increased treatment options for ischemic attacks during the acute time window, there are still limited therapeutic approaches available for improving long‐term post‐stroke recovery.[1, 2, 3, 4, 5] Angiogenesis and restoration of the blood‐brain barrier (BBB) in the ischemic penumbra play important roles in stroke recovery.
