Cerebrovascular Accidents During Mechanical Circulatory Support Clinical Sciences
Conclusions—Stroke is a major cause of morbidity and mortality in patients on LVAD support. Chronic obstructive pulmonary disease increases the risk of ischemic stroke, whereas dialysis may increase the risk of hemorrhagic stroke. Although any stroke increases mortality, post-LVAD hemorrhagic stroke was associated with higher mortality compared with ischemic stroke.

Vasculogenesis in Experimental Stroke After Human Cerebral Endothelial Cell Transplantation Basic Sciences
Conclusions— We found attenuation of behavioral and histological deficits coupled with robust vasculogenesis and neurogenesis in endothelial cell–transplanted stroke animals, suggesting that targeting vascular repair sets in motion a regenerative process in experimental stroke possibly via the VEGF pathway.

Neural Stem Cells Therapy for Ischemic Stroke: Progress and Challenges
AbstractIschemic stroke, with its high morbidity and mortality, is the most common cerebrovascular accident and results in severe neurological deficits. Despite advances in medical and surgical intervention, post-stroke therapies remain scarce, which seriously affects the quality of life of patients. Over the past decades, stem cell transplantation has been recognized as very promising therapy for neurological diseases. Neural stem cell (NSC) transplantation is the optimal choice for ischemic stroke as NSCs inherently reside in the brain and can potentially differentiate into a variety of cell types within the central nerv...

Mitochondrial Transfer as a Therapeutic Strategy Against Ischemic Stroke
AbstractStroke is a debilitating disease that remains the second leading cause of death and disability worldwide. Despite accumulating knowledge of the disease pathology, treatments for stroke are limited, and clinical translation of the neuroprotective agents has not been a complete success. Accumulating evidence links mitochondrial dysfunction to brain impairments after stroke. Recent studies have implicated the important roles of healthy mitochondria in neuroprotection and neural recovery following ischemic stroke. New and convincing studies have shown that mitochondrial transfer to the damaged cells can help revive cel...

Translating G-CSF as an Adjunct Therapy to Stem Cell Transplantation for Stroke
Abstract Among recently investigated stroke therapies, stem cell treatment holds great promise by virtue of their putative ability to replace lost cells, promote endogenous neurogenesis, and produce behavioral and functional improvement through their “bystander effects.” Translating stem cell in the clinic, however, presents a number of technical difficulties. A strategy suggested to enhance therapeutic utility of stem cells is combination therapy, i.e., co-transplantation of stem cells or adjunct treatment with pharmacological agents and substrates, which is assumed to produce more profound therapeutic benefi...

Cerebral Organoids Repair Ischemic Stroke Brain Injury
AbstractStroke is the second leading cause of death and main cause of disability worldwide, but with few effective therapies. Although stem cell-based therapy has been proposed as an exciting regenerative medicine strategy for brain injury, there are limitations. The developed cerebral organoids (COs) represent a promising transplantation source for stroke that remains to be answered. Here, we transplanted COs at 55  days and explored the feasibility in the rat middle cerebral artery occlusion (MCAO) model of stroke. COs transplantation at 6 h or even 24 h after MCAO significantly reduces brain infarct volume and improv...

Intrathecal Injection of Allogenic Bone Marrow-Derived Mesenchymal Stromal Cells in Treatment of Patients with Severe Ischemic Stroke: Study Protocol for a Randomized Controlled Observer-Blinded Trial
AbstractMesenchymal stromal cells (MSCs) can differentiate into multiple tissues. Preclinical studies have shown that MSC-based therapy is a potential new treatment approach for ischemic stroke. These results support the urgent need for further studies of MSC transplantation in the treatment of ischemic stroke in humans. Here, we develop a prospective, randomized, controlled, observer-blinded phase II trial to assess the clinical safety, feasibility, and therapeutic mechanisms of allogenic bone marrow-derived MSCs (BM-MSCs) by intrathecal infusion in the treatment of patients with cerebral infarction within the middle cere...
