    • Enhanced methods for the generation of medial ganglionic eminence (MGE) cells from pluripotent stem cells are provided that involve an additional step of contacting the cells with an activator of FGF8 signaling while differentiating Pax6+ cells progenitor cells into MGE cells with an activator of sonic hedgehog, and optionally a Wnt inhibitor. The activator of FGF8 signaling shifts the differentiation of the population of cells to NKX2.1+ MGE cells, rather than to CopuTFII+ caudal ganglionic eminence (CGE) cells. Methods for reatment of neurological disorders, such as epilepsy, by transplant of MGE cells, or GABAergic interneurons derived from human pluripotent stem cells, into a subject in need of treatment are also provided. Human pluripotent stem cell derived MGE cells when transplanted successfully suppress spontaneous seizures, e.g. in epilepsy. We also have developed a method to purify MGE cells and maturing interneurons from differentiated pluripotent stem cells using cell surface marker and molecular beacon technology.
    • 提供了用于从多能干细胞产生内侧神经节隆突(MGE)细胞的增强方法,该方法涉及使细胞与FGF8信号传导物接触的另外步骤,同时用Ponic6刺激素激活剂将Pax6 +细胞祖细胞分化成MGE细胞, 和任选的Wnt抑制剂。 FGF8信号的激活剂将细胞群的分化转移到NKX2.1 + MGE细胞,而不是CopuTFII +尾尾神经节隆起(CGE)细胞。 还提供了将需要治疗的受试者的神经系统疾病如癫痫,通过移植MGE细胞或来自人多能干细胞的GABA能中间神经元进行复原的方法。 人多能干细胞衍生的MGE细胞移植成功抑制自发性癫痫发作。 在癫痫。 我们还开发了一种使用细胞表面标记和分子信标技术从分化多能干细胞中纯化MGE细胞和成熟中间神经元的方法。

    • System(s) and method(s) are provided to enable imaging-based identification, detection, evaluation, and mapping of white matter microstructure and hemispheric organization of white matter in a central nervous system (CNS) structure afflicted by a neurological disease or disorder. Various embodiments exploit a set of diffusion tensor metrics to define a classification sub-space and determine a multivariate classifier through training data related to at least two groups of subjects: a first group of subjects afflicted by the neurological disease or neurological disorder, and a second group of subjects typically developing. The set of diffusion tensor metrics can be selected based at least on clinical information related to the neurological disease or neurological disorder and anatomy of CNS structure. Inclusion of tensor skewness asymmetry in such set yields an increase in sensitivity, specificity, accuracy, reliability, and predictive ability of the biological discrimination of subjects with and without a neurological disease or neurological disorder.
    • 提供了系统和方法,以使基于成像的识别,检测,评估和绘制由神经系统疾病或病症所折磨的中枢神经系统(CNS)结构中的白质微结构和白质的半球组织 。 各种实施例利用一组扩散张量度量来定义分类子空间,并且通过与至少两组受试者相关的训练数据确定多变量分类器:受神经疾病或神经障碍所折磨的第一组受试者,以及第二组 一组通常发展的科目。 可以至少基于与神经系统疾病或神经系统疾病和CNS结构的解剖学有关的临床信息来选择一组扩散张量度量。 在这种集合中包含张量偏度不对称性导致具有和不具有神经疾病或神经障碍的受试者的生物辨别的灵敏度,特异性,准确性,可靠性和预测能力的增加。
