| 1 | From the first human gene-editing to the birth of three-parent baby显示文摘Gene Editing refers to the process of making targeted modifications to the genome,such as the deletion,insertion or replacement of targeted DNA sequences(Pan et al.,2011).Gene editing technologies fundamentally improve our approaches to biological basic research,gene therapy,genetic improvement,etc.In the field of stem cells,gene editing can be used to modulate cell fate,such as generation of induced pluripotent stem cells(i PSCs)(Ding et al.,2015), | Xiaoxue Zhang Si Wang | 2016 | Science China(Life Sciences)2016,59,12: | 5 |
| 2 | 转录因子诱导人脐带间充质干细胞转分化为视网膜色素上皮样细胞的研究显示文摘目的探讨采用关键转录因子将人脐带间充质干细胞(human umbilical cord mesenchymal stem cells,h UC-M SCs)转分化为视网膜色素上皮(retinal pigment epithelium,RPE)样细胞的方法。方法通过流式细胞技术鉴定h UC-MSCs的表面标记分子;通过诱导h UC-MSCs分化成为脂肪、骨和软骨细胞确定其多系分化能力;采用慢病毒包装系统获得分别含有11个转录因子Sox2、Pax6、Rax、Six6、Nr2e1、Otx2、Lhx2、Crx、Mitf-A、Klf4和c-Myc的病毒,并通过感染h UC-MSCs来诱导h UC-MSCs向RPE样细胞分化。结果 h UC-MSCs表达CD29、CD44、CD73、CD90和CD105,但不表达CD11b、CD34,CD45和HLA-DR等分子标记,在成脂、成骨、成软骨分化培养基中可分化为脂肪、骨和软骨细胞。视网膜及RPE发育相关的关键转录因子能够将h UC-MSCs直接转分化为RPE样的细胞,并表达ZO-1、RPE65、Bestrophin-1(Best-1)、CK8/18、Cralbp、Mertk、Tyrosinase(Tyr)、PEDF等RPE细胞的特征分子。结论视网膜及RPE发育相关的关键转录因子可直接将h UC-MSCs分化为RPE样细胞。 | 王丽 范文斌 吕立夏 李鹏 田海滨 徐国彤 | 2015 | 同济大学学报(医学版)2015,36,5: | 4 |
| 3 | Application of stem cell-derived retinal pigmented epithelium in retinal degenerative diseases: present and future显示文摘As a constituent of blood-retinal barrier and retinal outer segment(ROS) scavenger, retinal pigmented epithelium(RPE) is fundamental to normal function of retina. Malfunctioning of RPE contributes to the onset and advance of retinal degenerative diseases. Up to date, RPE replacement therapy is the only possible method to completely reverse retinal degeneration. Transplantation of human RPE stem cell-derived RPE(h RPESC-RPE) has shown some good results in animal models. With promising results in terms of safety and visual improvement, human embryonic stem cell-derived RPE(h ESC-RPE) can be expected in clinical settings in the near future. Despite twists and turns, induced pluripotent stem cell-derived RPE(i PSC-RPE) is now being intensely investigated to overcome genetic and epigenetic instability. By far, only one patient has received i PSCRPE transplant, which is a hallmark of i PSC technology development. During follow-up, no major complications such as immunogenicity or tumorigenesis have been observed. Future trials should keep focusing on the safety of stem cell-derived RPE(SC-RPE) especially in long period, and better understanding of the nature of stem cell and the molecular events in the process to generate SC-RPE is necessary to the prosperity of SC-RPE clinical application. | Mingyue Luo Youxin Chen | 2018 | International Journal of Ophthalmology(English edition)2018,11,1: | 2 |
| 4 | 干细胞技术的研究热点领域与最新进展显示文摘近两年在干细胞分离鉴定、诱导分化、重编程调控机制、可塑性与疾病治疗等方面取得了重大突破,使得干细胞技术从一种实验室概念逐渐转变成用于医学治疗的实际手段。本文分别从以上四个热点领域介绍了2013-2014年国内外干细胞的最新研究进展,并对干细胞研究中存在的问题进行了初步分析,为研究者提供参考。 | 熊鹰 余欢欢 张龙威 王琦 | 2014 | 生物技术进展2014,4,4: | 2 |
| 5 | 家畜多能干细胞的研究现状与应用(英文)显示文摘多能干细胞(pluripotent stem cells,PSCs)包括从胚胎内细胞团中分离出的胚胎干细胞(embryonic stem cells,ESCs),外胚层干细胞(epiblast stem cells,Epi SCs),从原始生殖细胞(primordial germ cells,PGCs)分离出的胚胎生殖细胞(embryonic germ cells,EGCs)和诱导多能干细胞(induced pluripotent stem cells,iPSCs)。这些细胞都具有向各种类型细胞发育的潜能,因此,PSCs为再生医学的发展,人类基因疾病的动物模型的建立,异种器官移植和高质量抗病新品种的培育提供了有效的途径。迄今为止,PSCs在小鼠(Mus musculus)模型和人类物种已经做了大量研究,同时,家畜的ESCs和iPSCs也取得了有效的进展,表明其不仅可以应用于特定家畜优良品性的稳定遗传和优育,而且可以以家畜为载体生产人类需要的化学药品和抗体,甚至应用在人类疾病的临床前应用中。然而,家畜的ESCs相对来说是难分离和富集的,体外培养建立稳定的ESCs系具有更大的难度和挑战。近年来,得益于对家畜ESCs和相关iPSCs相关的持续研究,已初步揭示了家畜ESCs的独特生物学特性。PSCs已经成为生命科学和高科技农业和生物学一个创新的研究领域。在本文中,本文综述了家畜PSCs的发展历程与应用前景。 | 郑丽明 华进联 李光鹏 | 2016 | 农业生物技术学报2016,24,5: | 0 |
| 6 | 细胞直接重编程技术——疾病治疗的新策略显示文摘细胞直接重编程技术是近年来兴起的重要生物技术,其广泛的应用可为疾病的治疗、模型的构建、再生医学的研究提供了一个新的方向。细胞直接重编程技术不同于诱导性多能干细胞技术,它可将一种终末分化细胞直接转变为另一种终末分化细胞,跨越了分化细胞去分化以及再定向分化为特定功能细胞的过程,因而可避免多能干细胞本身可能带来的安全隐患。对体细胞直接重编程技术的研究现状作一综述。 | 张田田 齐晖 李富荣 | 2014 | 生命科学2014,26,4: | 0 |
