Adipose-derived mesenchymal stem cells attenuate ischemic brain injuries in rats by modulating miR-21-3p/MAT2B signaling transduction.

CONCLUSION: This study confirmed the protective effect of ADMSCs against ischemic brain injury exerted by suppressing miR-21-3p level and up-regulating MAT2B level. PMID: 31686458 [PubMed - in process]

The expressions of brain-derived neurotrophic factor (BDNF) and vascular endothelial growth factor (VEGF ) as neurotrophic factors were analyzed in both MSCs. hiMSCs or hcMSCs were intravenously administered into ischemic st...

Authors: Olaru DG, Olaru A, Kassem GH, Popescu-Drigă MV, Pinoşanu LR, Dumitraşcu DI, Popescu EL, Hermann DM, Popa-Wagner A Abstract Stroke has limited restorative treatment options. In search of new therapeutic strategies for the ischemic brain, cell-based therapies offered new hope, which has been, in the meanwhile, converted into a more realistic approach recognizing difficulties related to unfavorable environments causing low survival rates of transplanted neuronal precursors. Stem cell therapies are based on the transplantation of neuronal precursor cells (NPCs), adult stem cells propagated in cell culture o...

Abstract Stroke is a serious, life-threatening condition demanding vigorous search for new therapies. Recent research has focused on stem cell-based therapies as a viable choice following ischemic stroke, based on studies displaying that stem cells transplanted to the brain not only survive, but also cause functional recovery. Growth factors defined as polypeptides that regulate the growth and differentiation of many cell types. Many studies have demonstrated that combination use of growth factors may increase results by stimulation of endogenous neurogenesis, anti-inflammatory, neuroprotection properties, and enh...

Abstract Due to the limitation in treatment window of the rtPA (recombinant tissue plasminogen activator), the development of delayed treatment for stroke is needed. We previously reported that there is a difference in neurogenesis and neuroblast migration patterns in different mouse stroke models (proximal and distal middle cerebral artery occlusion models, pMCAo or dMCAo). Specifically, compared to robust neurogenesis and substantial migration of newly born neuroblasts in pMCAo model, dMCAo only illicit limited neurogenesis and migration of neuroblasts towards ischemic area. One potential reason for this differe...

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 volum...

CONCLUSIONS In a rat model of CIRI following MCAO, EA activated the NOTCH pathway, promoted the expression of miR-223, increased the number of NSCs, and reduced the expression of PTEN. PMID: 31883264 [PubMed - in process]

CONCLUSIONS: Highly arbourised neurons are more sensitive to ischaemic injury than NPs which did however develop marked vulnerability to prolonged injury with reoxygenation. These observations imply that therapeutic potential may be highly dependent of the developmental state of the neurons we aim to protect. PMID: 31837459 [PubMed - as supplied by publisher]
