Cell Stem Cell:干细胞来源的多巴胺神经元移植治疗帕金森

2014-11-12 佚名 生物谷

帕金森氏症是一种无法治愈的运动障碍,在世界各地影响数以百万计的人,但目前的治疗方案可能会导致严重的副作用,而且随着时间的推移会失去效力。 在Cell Stem Cell 发表的一项研究中,研究人员发现,从人胚胎干细胞(hESCs)衍生的神经元移植,可使帕金森氏病模型大鼠恢复运动功能。 我们的研究代表了临床前评估人类胚胎干细胞衍生的多巴胺神经元的一个重要里程碑,并为人类胚胎干细胞衍生的多巴

帕金森氏症是一种无法治愈的运动障碍,在世界各地影响数以百万计的人,但目前的治疗方案可能会导致严重的副作用,而且随着时间的推移会失去效力。

在Cell Stem Cell 发表的一项研究中,研究人员发现,从人胚胎干细胞(hESCs)衍生的神经元移植,可使帕金森氏病模型大鼠恢复运动功能。

我们的研究代表了临床前评估人类胚胎干细胞衍生的多巴胺神经元的一个重要里程碑,并为人类胚胎干细胞衍生的多巴胺神经元治疗帕金森氏病提供有用必要的证明。

随着时间的推移,目前可用的药物和手术治疗方案可能会失去效力,并导致严重的副作用,如不自主运动和精神问题。

为了严格评估人类胚胎干细胞衍生的多巴胺神经元为基础的治疗方法,Parmar和隆德大学研究主要作者Shane Grealish将人类胚胎干细胞衍生的多巴胺神经元移植到帕金森病大鼠模型控制运动的大脑区域中。

移植的细胞能存活,并在五个月内将多巴胺水平恢复正常,其结果是这种疗法能够恢复动物正常的运动功能。重要的是当移植到帕金森氏病模型大鼠,人类胚胎干细胞衍生的神经元的效能和效力类似于胎儿来源的神经元,这表明人类胚胎干细胞系衍生的神经元可以是一种可行的替代疗法。

Cell:干细胞来源胰岛B细胞 未来或可根治糖尿病

随着人们生活水平的提高,糖尿病也已经成为困扰许多人的"富贵病"之一。这也使得糖尿病药物市场成为了世界许多生物医药巨头的兵家必争之地。一直以来,药物研发人员都希望能够开发出一种与患者有高度相容性,且能够"智能"响应患者体内血糖变化而不必进行反复注射的疗法。而最近,哈佛大学的研究人员已经朝这一方向又迈出了可喜的一步。他们利用干细胞分化形成了大量的胰岛B细胞。与此前的一些类似实验不同,此次研究人员获得

干细胞“配方”为糖尿病患者带来曙光

  Douglas Melton 图片来源:B. D. COLEN   Douglas Melton与其他患者一样,在焦急地等待着治疗糖尿病的方法。他的儿子在婴儿时期就患上了糖尿病,女儿在14岁时也确诊患有该病。在过去20年中,这位美国哈佛大学干细胞研究所的发育生物学家一直致力于寻找攻克糖尿病的方法。   近日,他和同事报告了迈向该目标的重要一步:将人体干细

PLoS Genet:干细胞的神秘来源

当很多动物的生命开始之时,其机体细胞会接受指令立刻形成头部、尾部或者重要的器官,然而对于包括人类在内的哺乳动物而言,这个过程却是非常特殊的,哺乳动物胚胎的细胞会首先做出不同的选择,是变成保护性的胎座或是形成机体。 近日,来自密歇根州立大学的研究人员发表在国际杂志PLoS Genetics上的一篇研究报告指出了机体干细胞的来源,或为开发个体化疗法提供希望;多能干细胞可以变成机体任何类型的细胞,而多

Cell Rep:分化细胞可重新恢复为干细胞

近日研究发现,被称为“兼性”的一种干细胞和其它细胞共同组成器官和组织的一部分。显然这没有将这些细胞和其它细胞区分开来。然而,它们有一个非常特殊的特性,即它保存着一种再次成为干细胞的能力。这种现象偶尔发生在肝脏组织中,这种存在器官的组织细胞刺激组织生长,从而可以使移植器官再生。了解这些可使细胞保持再生能力的基础机制是再生医学的一个关键问题。 Jordi Casanova教授发表在《细胞》杂志上

Nature:中科院曾艺团队Nature发表论文 乳腺中发现多能干细胞

10月19日,国际顶尖学术期刊《自然》在线发表了中科院上海生命科学研究院国家重点实验室曾艺研究团队领衔完成的研究成果,宣布首次发现了乳腺中的多能干细胞,“刷新”了由国外科学家在2011年发表在《自然》上的乳腺干细胞只存在单潜能性的理论。该研究成果以干细胞为切入点,为靶向治疗乳腺癌提供新思路、奠定了应用的基础。 成年人的许多器官中存在着干细胞,也称组织干细胞。干细胞因为尚未分化、具有再生潜能而

Cell Stem Cell:科学家揭示在人工环境中成功复制天然干细胞发育的基准

近日,刊登在国际杂志Cell Stem Cell上的一篇研究论文中,来自加州大学洛杉矶分校(UCLA)的研究人员揭示了他们的研究或可实现在人工环境中复制天然干细胞;多能干细胞可以转化成为机体任何类型的细胞,科学家们通常利用许多不同的方法在一系列不同的环境中来培养干细胞,尽管如此,当前的培养技术仍然会影响多能干细胞最后分化的状态,于是本文中研究人员就阐释了如何在人工环境中实现干细胞的复制。 研
