    • The invention provides a method of culturing cells. The method generally includes five stages: (1) expansion of ES cells; (2) generation of embryoid bodies; (3) selection of CNS precursor cells; (4) expansion of CNS precursor cells; and (5) differentiation of CNS precursor cells. During the expansion phase, the CNS precursor cells are cultured in a media which includes at least one neurologic agent such as bFGF, SHH, and FGF8. The expanded CNS precursors are differentiated by withdrawal of at least one neurologic agent, typically, bFGF. Preferably, the differentiation media includes ascorbic acid. The method of the invention can be used to culture a variety of cells, preferably neuronal cells, including, but not limited to dopaminergic neuron cells, cholinergic neuronal cells and serotonergic neuron cells. The invention also provides a method for treating a neurological disorder, such as Parkinson's disease, a method of introducing a gene product into a brain of a patient, and an assay for neurologically active substances. The invention further provides a cell culture which includes differentiated neuron cells, of which at least about 20 % of the differentiated neurons are dopaminergic neurons.
    • 本发明提供了培养细胞的方法。 该方法通常包括五个阶段:(1)ES细胞的扩增; (2)胚状体的产生; (3)选择CNS前体细胞; (4)CNS前体细胞的扩增; 和(5)CNS前体细胞的分化。 在扩展阶段期间,将CNS前体细胞在包含至少一种神经药剂如bFGF,SHH和FGF8的培养基中培养。 扩大的CNS前体通过撤出至少一种神经药剂(通常为bFGF)而分化。 优选地,分化培养基包含抗坏血酸。 本发明的方法可用于培养各种细胞,优选神经元细胞,包括但不限于多巴胺能神经元细胞,胆碱能神经元细胞和5-羟色胺能神经元细胞。 本发明还提供治疗神经障碍如帕金森病的方法,将基因产物导入患者脑内的方法和神经活性物质的检测方法。 本发明进一步提供了包括分化的神经元细胞的细胞培养物,其中至少约20%的分化的神经元是多巴胺能神经元。
