New neurons are continuously generated from neural stem cells with astrocyte properties, which reside in close proximity to the ventricle in the postnatal and adult brain. In this study we found that microRNA-124 (miR-124) dictates postnatal neurogenesis in the mouse subventricular zone. Using a transgenic reporter mouse we show that miR-124 expression is initiated in the rapid amplifying proge...
This research reviews the treatment concept and procedures that are currently being practiced and studied on patients using stem cell grafts of fetal tissue as well as mesenchymal stem cells, alongside the nature of neurogenesis phenomenon in correlation with subventricular zone architecture in individuals with Parkinson’s disease in order to evaluate which treatment procedure has a higher effi...
We examined the development of the occipital lobe in fetal monkeys between embryonic day 37 (E37) and E108 in Nissl-stained and acetylcholine esterase (AChE)-reacted sections. We paid particular attention to features that distinguish the development of presumptive area 17. At E46 the neuroepithelium consists of a ventricular zone and a monolayer cortical plate sandwiched between a thin marginal...
γ-protocadherins (γ-pcdhs) are transmembrane receptor proteins ubiquitously expressed in the postnatal and adult mouse brain. γ-pcdhs are required for normal neuronal development as shown for spinal cord interneurons, retinal ganglion cells and cortical neurons. To test the role of γ-pcdhs during development of subventricular zone progenitor cells and their subsequent differentiation into olfac...
The functional significance of adult neural stem and progenitor cells in hippocampal-dependent learning and memory has been well documented. Although adult neural stem and progenitor cells in the subventricular zone are known to migrate to, maintain and reorganize the olfactory bulb, it is less clear whether they are functionally required for other processes. Using a conditional transgenic mous...
Stroke potently stimulates cell proliferation in the subventricular zone of the lateral ventricles with subsequent neuroblast migration to the injured striatum and cortex. However, most of the cells do not survive and mature. Extracellular Wnt proteins promote adult neurogenesis in the neurogenic niches. The aim of the study was to examine the efficacy of Wnt signaling on neurogenesis and funct...
introduction: multiple sclerosis (ms) is a chronic inflammatory demyelinating disease. in the present study, we investigated the response of subventricular zone (svz) adult stem cells in the experimental autoimmune encephalomyelitis (eae), an animal model of ms, and also the differentiation fate of these stem cells. methods: mice were immunized with mog peptide emulsified in complete freund&apo...
The expression patterns of the transcription factor, Sox-9, and of the nuclear factor, cDachsund-2, were examined in the developing chick telencephalon. Both genes were expressed in the ventricular zone and in the subventricular zone of the telencephalon during the period of neurogenesis. Whereas Sox-9 was not expressed in postmitotic tissues, cDachsund-2 was specifically expressed in the neost...
Introdution: Stroke is one of the most common diseases caused by occlusion or rupture of blood vessels in brain. It brings heavily loads for families and societies. Although some new strategies including treatment of tissue plasminogen activator have been applied in the clinic, these methods do not have perfect effect. Accordingly, more effective therapeutic strategies need to be developed...
