    • Differentiated neuronal cells suitable for transplantation in individuals with a dopamine deficiency are derived from progenitor cells. The progenitor cells are treated with at least one inducing agent such as retinoic acid for a time period sufficient to optimize expression of tyrosine hydroxylase. The cells intended for transplantation are optionally treated with a lithium salt to enhance bcl-2 production and survival. Optionally, the progenitor cells are co-cultured with Sertoli cells, bone marrow stem cells, or a combination thereof. The transplantation-ready cells are isolated and harvested. The resulting neuronal cells are purified and have a phenotype optimized to treat a dopaminergic deficiency, such as Parkinson's Disease. Optionally the neuronal cells can be implanted with Sertoli cells, bone marrow stem cells or a combination thereof. A purified human dopaminergic cell type is obtained by culturing NT2 cells and treated for about three weeks with an inducing agent, culturing for about two weeks with growth media without an inducing agent or mitotic inhibitor, culturing for about one week with at least one mitotic inhibitor, harvesting and placing in a diluent.
    • 适合于多巴胺缺乏症患者移植的分化神经元细胞来源于祖细胞。 用至少一种诱导剂如视黄酸处理祖细胞足够的时间以优化酪氨酸羟化酶的表达。 用于移植的细胞任选用锂盐处理以增强bcl-2的产生和存活。 任选地,祖细胞与支持细胞,骨髓干细胞或其组合共培养。 分离并收获移植准备的细胞。 所得神经元细胞被纯化并具有优化的表型以治疗多巴胺能缺乏症,例如帕金森病。 任选地,神经元细胞可以植入支持细胞,骨髓干细胞或其组合。 通过培养NT2细胞并用诱导剂处理大约三周,获得纯化的人多巴胺能细胞类型,用不含诱导剂或有丝分裂抑制剂的生长培养基培养约两周,用至少一种有丝分裂抑制剂培养约一周 ,收获并放入稀释剂中。
