Neuroprotective effect of secreted factors from human adipose stem cells in a rat stroke model.

Conclusions Our results suggest that RFs, selected from hASC-CM, may exert a neuroprotective effect in an ischemic stroke rat model that is comparable to the neuroprotective effect of full hASC-CM. The therapeutic effects of the RFs may be mediated by an anti-inflammatory mechanism and cell apoptosis inhibition. Hence, treatment with RFs can be considered a feasible substitute for stem cell therapy after stroke. PMID: 28948857 [PubMed - as supplied by publisher]

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...

Today's open access paper is a review of potential approaches that might be used as a basis for therapies to restore a more youthful level of neurogenesis in the aging mammalian brain. Neurogenesis is the process by which new neurons are created by neural stem cell populations and then integrated into neural networks. In adults, neurogenesis is essential to memory, learning, and the limited degree of regeneration that the brain is capable of enacting. Unfortunately, the supply of new neurons declines with age as the underlying stem cells become ever less active. Beyond making the aging brain more resilient, methods of incr...

Publication date: Available online 20 November 2019Source: Neurochemistry InternationalAuthor(s): Linlin Yuan, Shibo Sun, Xiaohan Pan, Liqin Zheng, Yuting Li, Jingyu Yang, Chunfu WuAbstractStroke is the leading cause of long-term motor disability and cognitive impairment beside the acute brain injury. Recently, neurogenesis has become an attractive strategy for the chronic recovery of stroke. Our previous study showed that pseudoginsenoside-F11 (PF11), an ocotillol-type saponin, isolated from leaves of Panax pseudoginseng subsp, exerted neuroprotective effects on stroke by alleviating autophagy/lysosomal defects and repres...

AbstractCortical injury, such as injuries after stroke or age-related ischemic events, triggers a cascade of degeneration accompanied by inflammatory responses that mediate neurological deficits. Therapeutics that modulate such neuroinflammatory responses in the aging brain have the potential to reduce neurological dysfunction and promote recovery. Extracellular vesicles (EVs) from mesenchymal stem cells (MSCs) are lipid-bound, nanoscale vesicles that can modulate inflammation and enhance recovery in rodent stroke models. We recently assessed the efficacy of intravenous infusions of MSC-EVs (24-h and 14-days post-injury) a...

Abstract Stroke is the leading cause of death and physical disability worldwide. Mitochondrial dysfunction has been considered as one of the hallmarks of ischemic stroke and contributes to the pathology of ischemia and reperfusion. Mitochondria is essential in promoting neural survival and neurological improvement following ischemic stroke. Therefore, mitochondria represent an important drug target for stroke treatment. This review discusses the mitochondrial molecular mechanisms underlying cerebral ischemia and involved in reactive oxygen species generation, mitochondrial electron transport dysfunction, mitochond...

Abstract Angiogenesis plays a central role in human physiology from reproduction and fetal development to wound healing and tissue repair/regeneration. Clinically relevant therapies are needed for promoting angiogenesis in order to supply oxygen and nutrients after transplantation, thus relieving the symptoms of ischemia. Increase in angiogenesis can lead to restoration of damaged tissues, thereby leading the way for successful tissue regeneration. Tissue regeneration is a broad field that has shown the convergence of various interdisciplinary fields, wherein living cells in conjugation with biomaterials have been...
