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...

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...

Transplantation of Directly Reprogrammed Human Neural Precursor Cells Following Stroke Promotes Synaptogenesis and Functional Recovery
AbstractStroke is one of the leading causes of long-term disability. Cell transplantation is a promising strategy to treat stroke. We explored the efficacy of directly reprogrammed human neural precursor cell (drNPC) transplants to promote functional recovery in a model of focal ischemic stroke in the mouse sensorimotor cortex. We show that drNPCs express neural precursor cell markers and are neurally committed at the time of transplantation. Mice that received drNPC transplants recovered motor function, irrespective of transplant vehicle or recipient sex, and with no correlation to lesion volume or glial scarring. The maj...

Cell-Based Therapies for Stroke: Promising Solution or Dead End? Mesenchymal Stem Cells and Comorbidities in Preclinical Stroke Research
Conclusion
The high prevalence of comorbidities in patients with stroke indicates the need for therapies in preclinical studies that take into account these comorbidities in order to avoid failures in translation to the patient. Preclinical studies are beginning to evaluate the efficacy of MSC treatment in stroke associated with comorbidities, especially hypertension, for ischemic and hemorrhagic stroke. Regarding aging and diabetes, only ischemic stroke studies have been performed. For the moment, few studies have been performed and contradictory results are being reported. These contradictory results may be due to the u...

Effect of Inflammation on the Process of Stroke Rehabilitation and Poststroke Depression
Conclusions
Stroke comprises ischemic stroke and ICH. The immuno-inflammatory process is involved in neural plasticity following events such as a hemorrhage or ischemic stroke. After ischemia, astrocytes, microglia, and MDMs play important roles during rehabilitation with the modulation of cytokines or chemokines, such as TNF-α and IL-1. Moreover, MiRNAs are also important posttranscriptional regulators in these glial mitochondrial responses to cerebral ischemia. ICH involves processes similar and different to those seen in ischemia, including neuronal injury, astrocytic and microglial/macrophage activation, and n...

Stroke Dysbiosis Index (SDI) in Gut Microbiome Are Associated With Brain Injury and Prognosis of Stroke
Conclusions: We developed an index to measure gut microbiota dysbiosis in stroke patients; this index was significantly correlated with patients' outcome and was causally related to outcome in a mouse model of stroke. Our model facilitates the potential clinical application of gut microbiota data in stroke and adds quantitative evidence linking the gut microbiota to stroke.
Introduction
Ischemic stroke imposes a heavy burden on society, with 24.9 million cases worldwide (1). Although intravenous thrombolysis and endovascular treatment greatly improve some patients' prognosis, the prognosis for most pa...

Combining Human Umbilical Cord Blood Cells With Erythropoietin Enhances Angiogenesis/Neurogenesis and Behavioral Recovery After Stroke
In conclusion, our results suggest that hUCBC infusion in combination with EPO administration demonstrates therapeutic efficacy in the treatment of stroke-induced injury by promoting neurogenesis and angiogenesis. Further research that delineates the therapeutic mechanism of systemically administered hUCBC and EPO is required.

World-Wide Efficacy of Bone Marrow Derived Mesenchymal Stromal Cells in Preclinical Ischemic Stroke Models: Systematic Review and Meta-Analysis
Conclusions: Our results show worldwide efficacy of BM-MSCs in improving functional outcomes in pre-clinical animal models of stroke and support testing these cells in clinical trials in various ranges of time windows using different delivery routes. The continued growing number of publications showing functional benefit of BM-MSCs are now adding limited value to an oversaturated literature spanning 18 years. Researchers should focus on identifying definitive mechanisms on how BM-MSCs lead to benefit in stroke models.

Using Dental Pulp Stem Cells for Stroke Therapy
Conclusion and Future Perspectives
Stem cell-based therapy is a promising alternative for stroke treatment. While stem cells from different sources, including induced PSC, ESC, MSC, and NSC, have been investigated, using NSC and enhancing the natural mechanisms is most appropriate for brain repair. In preclinical models of stroke, stem cell transplantation has led to positive outcomes through a variety of cellular and molecular mechanisms, many being mediated by the array of beneficial factors produced by the cells. Recent advances in cellular reprogramming have provided alternative sources of NSC to be investigated, allo...

Gut Microbiota-Derived Short-Chain Fatty Acids Promote Post-Stroke Recovery in Aged Mice.
Conclusions:This is the first study suggesting that the poor stroke recovery in aged mice can be reversed via "post-stroke bacteriotherapy" following the replenishment of youthful gut microbiome via modulation of immunologic, microbial and metabolomic profiles in the host.

The therapeutic potential of induced pluripotent stem cells after stroke: evidence from rodent models.
Abstract
Stroke is the second most common cause of death and the leading cause of disability in the world. About 30% of the people that are affected by stroke die within a year; 25% of the patients that survive stroke remain in need of care after a year. Therefore, stroke is a major burden for health care costs. The most common subtype is ischemic stroke. This type is characterized by a reduced and insufficient blood supply to a certain part of the brain. Despite the high prevalence of stroke, the currently used therapeutic interventions are limited. No therapies that aim to restore damaged neuronal tissue or to p...

Intestinal Epithelial Stem Cell Transplants as a Novel Therapy for Cerebrovascular Stroke
Brain Behav Immun. 2022 Oct 31:S0889-1591(22)00420-2. doi: 10.1016/j.bbi.2022.10.015. Online ahead of print.ABSTRACTAlmost 2/3rds of stroke survivors exhibit vascular cognitive impairment and a third of stroke patients will develop dementia 1-3 years after stroke. These dire consequences underscore the need for effective stroke therapies. In addition to its damaging effects on the brain, stroke rapidly dysregulates the intestinal epithelium, resulting in elevated blood levels of inflammatory cytokines and toxic gut metabolites due to a 'leaky' gut. We tested whether repairing the gut via intestinal epithelial stem cell (IE...

Exogenous Neural Stem Cells Transplantation as a Potential Therapy for Photothrombotic Ischemia Stroke in Kunming Mice Model
In this study, we explore the transplantation of exogenous neural stem cells (NSCs) as the potential therapy for the photothrombotic ischemia stroke in a Kunming mice model. After stroke, mice receiving NSC transplantation demonstrated a better recovery of brain function during the neurobehavioral tests. Histology analysis of the brain samples from NSC transplanted mice demonstrated a reduction of brain damage caused by stroke. Moreover, immunofluorescence assay for biomarkers in brain sections confirmed that transplanted NSCs indeed differentiated to neurons and astrocytes, consistent with the improved brain function afte...
