    摘要: The present invention relates generally to the field of cell biology of stem cells, more specifically the directed differentiation of pluripotent or multipotent stem cells, including human embryonic stem cells (hESC), somatic stem cells, and induced human pluripotent stem cells (hiPSC) using novel culture conditions. Specifically, methods are provided for obtaining neural tissue, floor plate cells, and placode including induction of neural plate development in hESCs for obtaining midbrain dopamine (DA) neurons, motorneurons, and sensory neurons. Further, neural plate tissue obtained using methods of the present inventions are contemplated for use in co-cultures with other tissues as inducers for shifting differentiation pathways, i.e. patterning.

    摘要: The present invention relates to undifferentiated human embryonic stem cells, methods of cultivation and propagation and production of differentiated cells. In particular it relates to the production of human ES cells capable of yielding somatic differentiated cells in vitro, as well as committed progenitor cells such as neural progenitor cells capable of giving rise to mature somatic cells including neural cells and/or glial cells and uses thereof. This invention provides methods that generate in vitro and in vivo models of controlled differentiation of ES cells towards the neural lineage. The model, and cells that are generated along the pathway of neural differentiation may be used for: the study of the cellular and molecular biology of human neural development, discovery of genes, growth factors, and differentiation factors that play a role in neural differentiation and regeneration, drug discovery and the development of screening assays for teratogenic, toxic and neuroprotective effects.

    摘要: Cultures of cells immunoreactive for glial fibrillary acidic protein (GFAP), as well as for the intermediate filament marker nestin were grown in a medium including epidermal growth factor (EGF) and serum. The cultured cells had the morphology of astroglial cells. The cells can be proliferated in adherent or suspension cultures. Depending on the culture conditions, the cells can be induced to differentiate to neurons or glial cells. The cultures can be expanded over a large number of passages during several months, and survive, express an astroglial phenotype and integrate well after transplantation into both neonatal and adult rat forebrain.
