摘要:
A method for reprogramming a fibroblast into a human induced neuronal cell (hIN) is described. The method comprises expressing heterologous reprogramming factors Bm2, Myt11, Zic1, Olig2, Asc11 or any combination thereof, in said fibroblast, and culturing the fibroblast in a medium comprising BDNF, NT3, GeM or any combination thereof. Biomarkers describing the obtained hiN cells are also presented. In another aspect, methods for screening compounds using the hiN cells is described.

摘要:
The disclosure provides that components of a PTEN cell signaling pathway may be utilized as therapeutic targets for treating, preventing, slowing the progression of or delaying the onset of a neurodegenerative disease or disorder. Such components that may be targeted include, phosphatase and tensin homologue (PTEN), glycogen synthase kinase 3 beta (GSK3β), and AKT. The subject matter disclosed herein relates to the therapeutic use of inhibitors of PTEN, inhibitors of GSK3β, or activators of AKT to treat a neurodegenerative disease or disorder in a subject. Compounds are disclosed which may be used in the methods provided.
摘要:
The invention is directed to methods for promoting the differentiation and maturation of embryonic and adult stem cells to dopamine neurons by increasing expression of the transcription factors Nurr1 and PitX3 in the stem cells. The invention provides embryonic and adult stem cells expressing Nurr1 and PitX3 from nucleic acid vectors, and dopamine neurons differentiated therefrom, and methods for treating a neuron-associated disorder, such as Parkinson's Disease, using the cells of the invention. The invention encompasses screening assays using the cells of the invention to identify compounds capable of inducing differentiation of stem cells to dopamine neurons.
