Conditioned medium obtained from human amniotic mesenchymal stem cells attenuates focal cerebral ischemia/ reperfusion injury in rats by targeting mTOR pathway
Publication date: Available online 28 October 2019Source: Journal of Chemical NeuroanatomyAuthor(s): Donya Nazarinia, Nahid Aboutaleb, Raheleh Gholamzadeh, Solmaz Nasseri Maleki, Behnaz Mokhtari, Mahin NikougoftarAbstractConditioned medium obtained from human amniotic mesenchymal stem cells (hAMSC-CM) was recently shown to have many antioxidant, antiapoptotic and proangiogenic growth factors. The present study was performed to investigate whether protective effects of hAMSC-CM against focal cerebral ischemia/ reperfusion (I/R) injury is associated with modulation of the mammalian target of rapamycin (mTOR) pathway.A rat mo...

Nitrogen-doped carbon nanocages and human umbilical cord mesenchymal stem cells cooperatively inhibit neuroinflammation and protect against ischemic stroke
This study aimed to explore the synergistic effects of nitrogen-doped carbon nanocages (NCNCs) and human umbilical cord mesenchymal stem cells (HUC-MSCs) on ischemic stroke and investigate the potential underlying mechanisms.Main methodsThe properties of NCNCs were analyzed by transmission electron microscopy, and the markers of HUC-MSCs were detected by flow cytometry. The cell toxicity of NCNCs was evaluated by MTT. Mice were induced cerebral infarction by transient middle cerebral artery occlusion (MCAO). NCNCs or HUC-MSCs or HUC-MSCs-NCNCs were intravenously injected thirty minutes after reperfusion. The infarct volume...

mfat ‐1 transgene protects cultured adult neural stem cells against cobalt chloride‐mediated hypoxic injury by activating Nrf2/ARE pathways
Abstract Ischemic stroke is a devastating neurological disorder and one of the leading causes of death and serious disability in adults. Adult neural stem cell (NSC) replacement therapy is a promising treatment for both structural and functional neurological recovery. However, for the treatment to work, adult NSCs must be protected against hypoxic‐ischemic damage in the ischemic penumbra. In the present study, we aimed to investigate the neuroprotective effects of the mfat‐1 transgene on cobalt chloride (CoCl2)‐induced hypoxic‐ischemic injury in cultured adult NSCs as well as its underlying mechanisms. The results ...
