近日,来自美国阿拉巴马大学的研究人员在国际学术期刊Cell Reports上发表了一项最新研究进展,他们找到利用化合物促进体细胞重编程获得诱导多能干细胞的新方法。

虽然人体内200多种不同的细胞类型具有相同的基因组,但是每种细胞类型都存在独特的基因表达程序。在体细胞重编程获得诱导多能干细胞的过程中,清除原始细胞的体细胞转录程序是一个关键事件。

在这项研究中,研究人员找到了一种新策略,他们利用小分子化合物干扰体细胞的转录记忆帮助体细胞重编程获得多能干性。研究人员发现靶向BET家族蛋白乙酰赖氨酸结合口袋的小分子化合物能够大大增强重编程过程。更进一步研究表明小分子化合物靶向BET的bromodomains能够下调或关闭成纤维细胞的体细胞基因表达,还会在重编程早期阶段导致成纤维细胞形态丧失。

研究人员提出了一个用于解释实验结果的模型:在正常的细胞分裂过程中,活跃的成纤维细胞基因在有丝分裂时期因为BET蛋白与乙酰化的染色质结合被打上标签,而RNA 聚合酶II则从染色质上脱落。在细胞分裂间期开始的时候,这些标签会指导聚合酶回到需要转录的基因上,随后开始基因的转录。而加入化合物抑制剂之后,因小分子化合物与BET蛋白的结合,在有丝分裂阶段活跃的成纤维细胞基因被去掉标签,这会导致成纤维细胞相关基因的表观遗传记忆被清除,当重新进入细胞分裂间期,与成纤维细胞有关的基因转录无法启动,增强了体细胞重编程变为诱导多能干细胞的能力。

综上所述,研究人员通过实验证明借助靶向BET bromodomains的化合物清除体细胞的转录记忆可以促进细胞发生命运转变。该研究为提高诱导多能干细胞的得率提供了一个新策略。

在一项新的研究中,来自美国斯坦福大学医学院的研究人员发现利用人诱导性多能干细胞(iPS细胞)制造的心肌细胞忠实地反映供者天然的心脏组织中关键基因的表达模式。因此,这些细胞能够被用来预测病人是否可能经历药物相关的心脏损伤。相关研究结果于2016年8月18日在线发表在Cell Stem Cell期刊上,论文标题为“Transcriptome Profiling of Patient-S

盘点:大放异彩的“万能细胞”---干细胞

干细胞(stem cells,SC)是一类具有自我复制能力(self-renewing)的多潜能细胞,干细胞是一种未充分分化,尚不成熟的细胞,具有再生各种组织器官和人体的潜在功能,被称为“万能细胞”。跟APSC多能细胞一样,是一类具有自我复制和多向分化潜能的原始细胞,它也是维持生命不息的最基本动力,多功能活化细胞抗衰老就是通过利用由自体采集的组织细胞,经实验室分离、培养后,将增殖的干细胞注入回
