Cell Stem Cell:开发出在体外长期培养成体干细胞的方法

2016-06-18 佚名 生物谷

在一项新的研究中,来自美国麻省总医院(MGH)等机构的研究人员开发出的一种新方法可能引发成体干细胞培养领域变革。研究人员描述了获得来自在日常治疗肺部疾病期间收集的各种组织样品中的气道干细胞(airway stem cell),并对它们进行增殖。这种方法似乎也可用于几种其他的组织,如皮肤、胃肠道内壁和生殖道。相关研究结果于2016年6月16日在线发表在Cell Stem Cell期刊上,论文标

在一项新的研究中,来自美国麻省总医院(MGH)等机构的研究人员开发出的一种新方法可能引发成体干细胞培养领域变革。研究人员描述了获得来自在日常治疗肺部疾病期间收集的各种组织样品中的气道干细胞(airway stem cell),并对它们进行增殖。这种方法似乎也可用于几种其他的组织,如皮肤、胃肠道内壁和生殖道。相关研究结果于2016年6月16日在线发表在Cell Stem Cell期刊上,论文标题为“Dual SMAD Signaling Inhibition Enables Long-Term Expansion of Diverse Epithelial Basal Cells”。

“这种新方法为研究哮喘或慢性阻塞性肺病(chronic obstructive pulmonary disease, COPD)等任何一种气道疾病开辟了新途径”,论文通信作者、MGH再生医学中心科学家、哈佛医学院医学副教授Jayaraj Rajagopal博士说,“尽管我们在过去仅能够允许成体干细胞增殖几代,但是如今我们能够在多家实验室持续几年培养出足够多的成体干细胞用于实验。我们的方法也是非常简单的,避免了之前培养系统的复杂性,使得很多实验室更容易采用它。”

人们已提出很多假设来解释在体外培养时只能有限地维持成体干细胞的性能,包括保护染色体末端的端粒丢失和细胞衰老。Rajagopal团队着重关注一种已知调节细胞生长和关键性分化过程的细胞信号通路。当被TGF-β和骨形态发生蛋白(BMP)等蛋白激活时,这种信号通路利用胞内蛋白SMAD将信号传递到细胞核。

在这项研究中,研究人员研究了抑制SMAD通路是否能够通过阻断体外培养的成体干细胞分化而促进它们增殖。在一系列实验中,他们首先证实TGF-β/BMP和SMAD信号通路在已分化的细胞中是有活性的,但在成体干细胞中是没有活性的。在发现阻断SMAD信号通路能够阻断小鼠气道干细胞分化后,他们发现同时阻断TGF-β/BMP和SMAD信号通路允许气道干细胞增殖很多代。他们能够从支气管镜检(bronchoscopy)时采集的样品中获得人气道干细胞。引人注目的是,他们也成功地从一些痰液样品---咳嗽时从呼吸道排除的液体---中获得人气道干细胞并对它们进行维持。

研究人员发现这一方法也可用于很多组织,包括皮肤、食道和乳腺等。这些器官中有不少当前还不能在体外培养,因此,还有待观察这些领域的科学家们是否能够培养来自利用其它侵入性最小的方法(如收集分泌物)获得的样品中的干细胞。如果经证实确实能够的话,那么它代表着个人化疾病研究方法取得重大进展。

Stem Cells:脐带血干细胞有望治疗异位性皮肤炎

异位性皮肤炎(atopic dermatitis)这一病名是由瓦也斯(Wise)和苏兹伯格(Sulzberger)在1933年最早提出的。异位性皮肤炎,又名异位性湿疹或遗传过敏性湿疹,是一种与遗传有密切关系的皮肤疾病,因遗传导致皮肤异常而发生病变,会反复发作且搔痒难当即异常敏感,好发于婴幼儿时期,也因此,有些人会称之为“婴儿湿疹”。异位性皮肤炎属于慢性、复发性、瘙痒性皮肤病。异位性的含义:(1

基因治疗新篇章!葛兰素史克干细胞基因疗法Strimvelis获欧盟批准治疗ADA-SCID

英国制药巨头葛兰素史克(GSK)基因疗法Strimvelis近日在欧盟监管方面传来喜讯。欧盟委员会(EC)已批准Strimvelis用于腺苷脱氨酶(ADA)缺乏性重度联合免疫缺陷症(ADA-SCID)儿科患者。ADA-SCID是一种非常罕见的疾病,患者出生时便不具备健康、健全的免疫系统功能,导致对日常感染失去抵抗力。据估计,在欧洲,每年大约确诊15例ADA-SCID儿科患者。Strimveli

Nature:靶向攻击p53和c-MYC可选择性清除白血病干细胞

在一项新的研究中,来自英国格拉斯哥大学、曼彻斯特大学和澳大利亚墨尔本大学的一个跨学科研究团队揭示出慢性粒细胞白血病(chronic myeloid leukaemia, CML)的阿喀琉斯之踵(即致命弱点),并且发现在小鼠体内成功地靶向攻击这种弱点和根除这种疾病的药物。相关研究结果于2016年6月8日在线发表在Nature期刊上,论文标题为“Dual targeting of p53 and

迎来黄金时代的无创治疗

未来医疗的发展方向将有两大趋势:一是以基因、干细胞技术为主的个性化治疗,另外一个就是以超声聚焦技术为主的无创治疗。这是曾任马里兰大学医学中心院长和美国国立卫生研究院Magnuson医学中心院长的斯蒂芬·申弗在其著作《医疗大趋势:明日医疗》中所作的描述。其实,早在2011年,美国的《时代周刊》杂志就将超声聚焦技术列为新世纪的50项最重要的发明之一。甚至国际超声学会主席Crum教授还作出这样的预测:2

哈佛干细胞专家:让骨髓移植更安全的方法

最近,哈佛大学干细胞研究所(HSCI)的科学家们,开发出了一种使骨髓——造血干细胞——移植更安全的疗法,因此,可能更广泛适用于数以百万计患有血液疾病(如镰状细胞性贫血、地中海贫血和艾滋病)的人。 目前,骨髓移植是治疗这些血液疾病唯一有效的疗法。但是,对于新的、移植的干细胞来说,要发挥它们的作用,首先必须“驱逐”或杀死有缺陷的干细胞。要做到这一点,就需要病人忍受化疗和辐射——对身体的恶性攻击,

Nat Commun:新研究成功应用干细胞疗法延缓小鼠亨廷顿氏病进展

近日,研究人员成功地利用健康人类脑细胞延缓了亨廷顿氏病小鼠模型的疾病进展,缓解了疾病症状。相关研究结果发表在国际学术期刊Nature Communication上,这项研究为治疗亨廷顿氏病提供了一个新方法。   亨廷顿氏病是一种遗传性神经退行性疾病,主要是由于负责运动控制的中型多棘神经元发生损伤所导致的。患有该病的病人会出现运动失调,认知下降以及抑郁等病症,目前仍然没有治疗或延缓
