美国研究人员4月28日说,他们用一些化合物把皮肤细胞成功转化为心肌细胞与脑细胞,这一重要突破为将来利用化学药物修复和再生组织器官奠定基础。

这项研究由加利福尼亚大学旧金山分校华人科学家丁胜教授领导(目前也在清华大学药学院任院长),其成果以两篇论文的形式分别发表在新一期美国《科学》与《细胞-干细胞》杂志上。其中Science文章第一作者是曹楠。


把皮肤细胞转化为心肌细胞或脑细胞,从前用转基因方法做到过,但用小分子药物不仅可大大提高效率和速度,还可以避免给细胞添加基因可能导致的潜在危险,例如产生肿瘤。

由于成人心脏产生新细胞的能力极其有限,此前科学家曾尝试通过移植成人心肌细胞或干细胞来治疗受损心脏,但效果不理想,移植细胞很难存活,干细胞转化效率较低。

在发表于《科学》杂志的第一项研究中,丁胜等人对89个已知会促使细胞重新编程的小分子进行筛选,找到9种化合物的组合可把人类皮肤细胞转化为心肌细胞。这大体分为两步,首先让皮肤细胞进入一种类似多能干细胞的状态,多能干细胞在特定器官中可分化为多种细胞类型,其次把这些细胞转化为心肌细胞。

研究人员表示,在把这些改造细胞植入发生心肌梗塞的小鼠体内后,小鼠受损心脏部分愈合。

在另一项研究中,研究人员利用类似方法把小鼠皮肤细胞转化为神经干细胞,所用化合物组合也包括9种小分子药物,与第一项研究使用的9种化合物部分重叠。

在把所获得的神经干细胞植入小鼠体内后,这些神经干细胞可自发转化为3种基本的脑细胞类型:神经元、少突胶质细胞和星形胶质细胞。这种神经干细胞还能自我复制,因此很适合用于治疗神经退行性疾病或脑损伤。

丁胜说,他们做了大量的体外细胞和动物体内的验证实验,这些研究成果代表着细胞治疗和体内器官再生领域“全新的突破”。

他说,未来病人也许可以通过服用药物,来修复和再生自己的组织器官,比如心脏衰竭或帕金森病患者服药后,其心脏或脑受损部分可利用现有的组织细胞再生,这一过程与蝾螈或蜥蜴断肢再生很相似。

丁胜

世界著名的生物学机构美国斯克里普斯研究所化学系博士,目前在该研究所任教授,是一位年轻有为、非常具有潜力和实力的科学家。目前已发表了35篇原创性的、前沿性的文章,18篇评论及其他论著,拥有了16项专利,多次作为专家担任美国多个重大基金或项目的评审。丁胜博士具有合成化学、干细胞生物学及药物研发技术多元的专业背景,并创造性地开拓了“干细胞化学生物学”这一前沿性新领域。
   
丁胜博士研究团队早从2004年就开始进行小分子化合物诱导单功能细胞转变为多功能细胞方面的研究。其团队开创了用4个蛋白诱导ips的技术先河。这是目前“唯一”一个完全避免基因操作,避免改变基因组的ips诱导方法。在ips技术研究和发展中创造多个首例并成功首次合成小分子化合物QS11、Pluripotion和小分子化合物逆转剂reversine.这些成果被Science、Nature、华尔街等著名媒体报导,部分成为美国一流的生物技术公司成立的基本概念。
   
到目前为止,该团队在这一领域一直保持着领先。其中在一些方面第一次对生命科学领域的某些新的概念和技术进行了阐释和解析。为其他学者们在接下来的研究中提供了重要的参考依据,启发性意文。
   
丁博士在该学科的成就使得权威杂志The Scientist在年度盘点中,两度垂青这个青年科学家:丁胜博士所创的蛋白诱导ips技术被评为“年度最佳创新技术”,与此同时,丁胜博士也被The Scientist评选为“生命科学年度人物”。

2015年,清华大学成立药学院,丁胜担任首任院长。

     新西兰奥克兰大学大脑研究中心的研究人员成功地将人皮肤细胞直接地转化为不成熟的脑细胞或者说神经前体细胞(neural precursor cell)。他们开发出一种快速和有效的方法来完成这种转化,同时也不用经历转化为类似胚胎干细胞的诱导性多能干细胞中间阶段。     Bronwen Connor说,“对全世界的干细胞

Nature:人皮肤细胞可变身功能性肝细胞

再生医学的力量使得科学家们现在能够将皮肤细胞转化为与心脏细胞、胰腺细胞甚至神经元非常相似的细胞。然而,事实证明拯救生命疗法的重要前提条件:获得完全成熟的细胞生成方法比想象中要困难得多。现在,来自Gladstone研究所和加州大学旧金山分校(UCSF)的科学家们取得了一项重大的突破:他们发现了一种方法可将皮肤细胞转化为成熟的、全功能的肝细胞,甚至在移植到模拟肝衰竭的实验室遗传修饰动物体内后也能自身旺

PNAS:ETV2将皮肤细胞直接转化为血管内皮细胞!

近日,刊登在国际杂志PNAS上的一篇研究论文中,来自日本庆应大学医学院(Keio University School of Medicine)的研究人员通过研究表示,他们可以利用一种名为ETV2的ETS转录因子直接将人类机体的成纤维细胞转化成为功能性的内皮细胞。 内皮细胞可以形成机体脉管系统来为维持我们机体的健康,比如向组织或器官供给营养物质及氧气等,因此,利用某些转录因子将非血管性的细胞转

Nat Neurosci:历时六年,科学家成功将皮肤细胞转化为痛觉神经元

经过六年的努力,波士顿儿童医院(BCH)哈佛大学干细胞研究所(HSCI)和哈佛大学干细胞与再生生物学系(HSCRB)的研究人员终于成功地将老鼠和人的皮肤细胞转化成了痛觉神经元,该神经元响应一系列导致急性和炎性疼痛的刺激。这六年间,科学家们经历了无数次的失败,很多时候甚至让他们觉得这一切的努力都是徒劳的。 这个在培养皿中的疼痛接收疾病模型将有助于加深对多种不同类型疼痛机制的理解,鉴别为什么不同
