Spontaneous Recovery of Upper Extremity Motor Impairment After Ischemic Stroke: Implications for Stem Cell-Based Therapeutic Approaches
AbstractPreclinical studies suggest that stem cell therapy (SCT) may improve sensorimotor recovery after stroke. Upper extremity motor impairment (UEMI) is common after stroke, often entailing substantial disability. To evaluate the feasibility of post-stroke UEMI as a target for SCT, we examined a selected sample of stroke patients potentially suitable for SCT, aiming to assess the frequency and recovery of UEMI, as well as its relation to activity limitations and participation restrictions. Patients aged 20 –75 years with first-ever ischemic stroke, and National Institutes of Health Stroke Scale (NIHSS) scores 1–18,...

Diffusion Tensor Imaging of Corticospinal Tract Recovery after Intra-arterial Mesenchymal Stem Cell Infusion in a Canine Stroke Model (P1.266)
Conclusions:Serial DTI-DTT imaging after IA MSCs therapy in large animal stroke model appears to have a trend towards higher change in FA. These findings could support further development of DTI-DTT biomarkers to measure neurologic recovery in experimental models as well as early clinical trials of novel stroke therapies.Disclosure: Dr. Guada has nothing to disclose.

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.

Disruption of Sonic Hedgehog Signaling Accelerates Age-Related Neurogenesis Decline and Abolishes Stroke-Induced Neurogenesis and Leads to Increased Anxiety Behavior in Stroke Mice
In this study, using conditional knockout (cKO) of SHH signaling receptorSmo gene in NSCs, we show a decreased neurogenesis at both SVZ and SGZ in young-adult mice and an accelerated depletion of neurogenic cells in the process of aging suggesting that SHH signaling is critical in maintaining neurogenesis during aging. Behavior studies revealed that compromised neurogenesis inSmo cKO mice leads to increased anxiety/depression-like behaviors without affecting general locomotor function or spatial and fear-related learning. Importantly, we also show that NSCs with a  cKO of SHH signaling abolishes stroke-induced neurogenesi...

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...

Role of Exosomes as a Treatment and Potential Biomarker for Stroke
AbstractApproximately, 16 million strokes occur worldwide each year, causing 6 million deaths and considerable disability, implying an enormous social, individual health, and economic burden. Due to this high incidence, strategies to promote stroke recovery are urgently needed. Research into new therapeutic approaches for stroke has determined that intravenous administration of mesenchymal stem cells (MSCs) is a good strategy to improve recovery by amplifying mechanisms implicated in brain plasticity. Recent studies have demonstrated the efficacy of MSCs in stroke, with no need for them to reach the area of brain injury. A...

Neural Stem Cell Extracellular Vesicles Disrupt Midline Shift Predictive Outcomes in Porcine Ischemic Stroke Model
This study investigated the utility of MRI as a predictive measure of clinical and functional outcomes when a stroke intervention is withheld or provided, in order to identify biomarkers for stroke functional outcome under these conditions. Fifteen MRI and ninety functional parameters were measured in a middle cerebral artery occlusion (MCAO) porcine ischemic stroke model. Multiparametric analysis of correlations between MRI measurements and functional outcome was conducted. Acute axial and coronal midline shift (MLS) at 24 h post-stroke were associated with decreased survival and recovery measured by modified Rankin scale...

Extracellular Vesicles Derived from Neural Progenitor Cells ––a Preclinical Evaluation for Stroke Treatment in Mice
AbstractStem cells such as mesenchymal stem cells (MSCs) enhance neurological recovery in preclinical stroke models by secreting extracellular vesicles (EVs). Since previous reports have focused on the application of MSC-EVs only, the role of the most suitable host cell for EV enrichment and preclinical stroke treatment remains elusive. The present study aimed to evaluate the therapeutic potential of EVs derived from neural progenitor cells (NPCs) following experimental stroke. Using the PEG technique, EVs were enriched and characterized by electron microscopy, proteomics, rt-PCR, nanosight tracking analysis, and Western b...

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...
