Abstract
- Background: This investigation tested the hypothesis that preactivated and disaggregated shape-changed platelets (PreD-SCP) and human embryonic stem cell-derived exosomes (hESC-Exo) treatments can reduce brain-infarct area (BIA) in rat with preservation of neurological function following acute ischemic stroke (AIS) induced by left middle-cerebral artery occlusion. Materials and Methods: Adult-male Sprague-Dawley rats (n=24) were randomly divided into group 1 (sham-control), 2 (AIS), 3 [AIS + PreD-SCP (3.0x108 cells)] and 4 (AIS + hESC-Exo, 100 μg). PreD-SCP and hESC-Exo were administered intravenously at 2/6/24 hours after the AIS procedure for animals in group 3 and 4, respectively. All animals were euthanized by day-28 post-AIS. Results: Brain infarct area (BIA) measured by histopathology was significantly larger in group 2 than that in other groups, and significantly larger in group 3 and 4 than that in group 1 (p
