  1. SCIENTIFIC OVERVIEW

    我的研究兴趣集中在多能干细胞(ES/iPSC细胞)多能性维持和分化的机制。在清华大学攻读博士学位期间的研究领域主要是转录因子如Oct4Sox2Nanog FoxD3等在小鼠ES细胞中多能性调控的作用机制,在阐述转录因子维持胚胎干细胞多能性机制方面作出了重要贡献,这些研究成果在干细胞领域得到了广泛引用,达390次。其后在2005-2009 年加入了威斯康星大学-麦迪逊James Thomson 实验室进行博士后研究,并主要致力于更有应用前景的人胚胎干细胞的调控研究。在阐述组蛋白修饰介导的表观遗传调控人多能性方面作出了贡献。期间的研究内容涉及多种层面的生物学调控过程,包括转录因子调控、组蛋白修饰介导的表观遗传(epigetics)调控、TGFβFGF2 等信号传导通路的调控等。研究成果分别发表在JBCFASEB JCell Stem CellCell等有影响力的杂志,其中单篇论文的最高被他人引用次数已达274次。

    我于2010年加入到中科院广州生物医药与健康研究院后,结合积累多年来人多能干细胞的研究经验,目前主要致力于探讨将人诱导性多能干细胞(iPS)用于临床疾病治疗的研究。主要是针对血液、神经等系统的疾病,探讨如何诱导并利用病人的iPS细胞分化获得有功能的造血干细胞、神经干细胞用于相关疾病的移植治疗。通过筛选调节细胞多能性维持和分化的信号分子,探讨信号分子、表观遗传学、转录因子等生物学层面调控多能性和分化的机制。在此基础上优化诱导条件,为进一步临床应用打下基础。已在转分化获得神经干细胞方向取得突破。

    我于2011年作为课题负责人参加了中科院干细胞战略性重大先导专项,是国家重大研究计划(973)项目首席科学家,2012年入选中国科学院百人计划2014年获批国家自然科学基金面上项目一项,累计获得科研经费超过两千八百万元。作为第二完成人参与干细胞多能性与重编程机理研究项目,获得2013年国家自然科学奖二等奖一项;作为第三完成人参与诱导多能干细胞机理与技术研究项目,获得2010年广东省科学技术奖励一等奖一项。2013年联合指导的毕业博士生王立辉同学获得中科院朱李月华奖学金,我被评为朱李月华优秀教师。现在,实验室有研究生10名,有3名副研究员,8名研究助理。

  2. RESEARCH SUMMARY

干细胞研究的最终目的是获得有功能的具有治疗作用的特定细胞类型以实现疾病的治疗。围绕这一目标,只有彻底了解干细胞干性维持及定向分化的分子调控,才能有效的将其分化为有功能的治疗用细胞。

我们团队近期将病人的尿液细胞在3周内诱导转变为神经干细胞(2013Nature Methods),为神经系统疾病的移植治疗带来了新的希望。这一发现引起了国内外的广泛关注,当期Nature Methods配发点评文章,并被人民日报头版报道。这一技术在国际上是第一次获得非整合的诱导性人神经干细胞,具有时间快、效率高、无病毒整合等优点,绕开了iPS细胞的中间状态,从而避免了iPS细胞可能存在的风险。目前,我们正致力于建立GMP条件下尿液神经干细胞的制备及临床前动物模型研究,有望在未来五年开展临床应用研究。

我们团队建立了将尿液分离细胞诱导为非整合的iPS细胞的技术,该技术不用病毒、不使用血清、不使用动物源饲养层、不使用致癌基因c-MYC。目前已经构建了具多种遗传背景的iPS细胞系,包括地中海贫血,血友病,ALS等(2013 PLOS ONE)。我们进一步通过TALENZFNCRISPR等技术手段进行基因修饰,目前已经完成地中海贫血的基因修复,基因敲除,报告基因的定点敲入等。

我们团队建立了将人源ESiPS细胞与OP9共培养分化为造血干祖细胞的技术平台,利用流式细胞仪、集落行成、免疫缺陷小鼠造血系统重建等手段对分化过程进行监测。目前,正在应用这个平台进行造血相关调控因子的功能研究,从分子和细胞水平上进一步调查这些因子对于造血分化过程的影响。

为更好的研究干细胞的特性、异质性、估功能细胞的安全性,以及通过比较分析发现候选基因等目的,我们建立了基于MiSeqNextSeq二代测序平台。目前已经优化和实现了测序文库的制备和上机测试,成功进行了干细胞和衍生细胞的CHIP-seqRNA-seq的测序和后续分析。
