Malignant gliomas manifest frequent tumor recurrence after surgical resection and/or other treatment because of their nature of invasiveness and dissemination. The recognized brain tumor-tracking property of neural progenitor/stem cells opened the possibility of targeting malignant brain tumors using neural progenitor/stem cells. We and others have previously shown that fetal neural progenitor/...

Angiogenesis and neurogenesis are coupled processes. Using a coculture system, we tested the hypothesis that cerebral endothelial cells activated by ischemia enhance neural progenitor cell proliferation and differentiation, while neural progenitor cells isolated from the ischemic subventricular zone promote angiogenesis. Coculture of neural progenitor cells isolated from the subventricular zone...

background degenerative retinal diseases, including age related macular degeneration, glaucoma, and hereditary retinal dystrophies are major causes of blindness. the principal defect in these diseases is cell loss which is amenable to both cell based neuroprotective and neuroregenerative therapies. to briefly review the lines of research and potential candidates for cell based therapies among r...

Neurodegenerative diseases are the hereditary and sporadic diseases which are characterized by progressive neuronal loss of the nervous system and are emerging as the leading cause of death, disabilities, and a socioeconomic burden due to an increase in life expectancy. There are many neurodegenerative diseases including Alzheimer’s disease, Parkinson’s, disease, amyotrophic lateral...

Human embryonic stem cells (hESCs) are able to proliferate in vitro indefinitely without losing their ability to differentiate into multiple cell types upon exposure to appropriate signals. Particularly, the ability of hESCs to differentiate into neuronal subtypes is fundamental to develop cell-based therapies for several neurodegenerative disorders, such as Alzheimer's disease, Huntington's di...

In the developing neocortex, cells in the ventricular/subventricular zone are largely multipotent neural stem cells and neural progenitor cells. These cells undergo self-renewal at the early stage of embryonic development to amplify the progenitor pool and subsequently differentiate into neurons. It is thus of considerable interest to investigate mechanisms controlling the switch from neural st...

Human neural progenitor cells provide a source for cell replacement therapy to treat neurodegenerative diseases. Therefore, there is great interest in mechanisms and tools to direct the fate of multipotent progenitor cells during their differentiation to increase the yield of a desired cell type. We tested small molecule inhibitors of glycogen synthase kinase-3 (GSK-3) for their functionality a...
