近日,一项刊登在国际杂志Science上的研究报告中,来自加利福尼亚大学等机构的研究人员通过联合研究开发出了一种新方法,该方法能够对小鼠胚胎干细胞进行重编程使其能够表现出颇似受精卵一样的发育特性。研究者指出,这些全能样的干细胞不仅能够产生发育胚胎中所有的细胞类型,还能够产生一些特殊类型的细胞,这些细胞能够促进胚胎和母体之间的营养交换。

这项研究或将帮助研究人员理解早期胚胎发育过程中的分子决策,同时也将扩展干细胞所产生的组织类型的“目录”,对于后期再生医学研究以及基于干细胞疗法的开发也至关重要。一个受精卵拥有完全的发育潜能,其能够产生所需的所有细胞类型,包括发育中的胚胎以及额外的胚胎组织,胎盘哺乳动物、胚外组织比如胎盘以及卵黄囊的特性对于胎儿和母亲之间进行营养和废物交换非常重要。

相比较而言,很多胚胎干细胞和诱导多能干细胞往往会因发育潜能而更受限制,其能够形成胚胎细胞类型,但却并不能形成胚外组织;受精卵能够产生胚胎和胚外组织的能力被认为其具有一种“全能性”,这是在胚胎发育早期阶段中唯一能够看见的最终干细胞状态。研究者Lin He教授指出,对胚胎发育的研究更大程度得益于胚胎干细胞的培养系统以及对诱导多能干细胞的研究,这些实验系统能够帮助科学家深入剖析胚胎发育过程中负责特殊细胞命运决策的关键分子途径,但当精子和卵子结合形成受精卵后,受精卵所具有的特殊发育潜能往往很难被研究,这往往是因为缺少研究材料以及细胞培养实验系统。

本文研究不仅及时了调节全能样干细胞状态的分子机制,同时也为研究干细胞全能性提供了一种强大的细胞培养实验系统。胚胎干细胞被认为具有多潜能性,因为其能够转变成为机体中任何类型的细胞,同时在过去几十年的研究中胚胎干细胞也给科学家们带来了很多惊喜,研究人员能够在实验室对其研究来阐明控制胚胎和胎儿机体特殊组织发育的遗传开关,同时胚胎干细胞还能够替换掉机体中损坏的组织,比如糖尿病患者的胰腺细胞或充血性心力衰竭患者心脏中的心肌细胞等,当然这些干细胞还能够帮助科学家们对早期阶段的遗传病进行研究探索。

如今科学家们利用“鸡尾酒”混合制剂或转录因子来处理成熟的体细胞就能够获得多能干细胞,从而就能够使得这些细胞具有和胚胎干细胞一样的特性,这些人工制造出的干细胞也被称为诱导多能干细胞(iPSCs);然而胚胎干细胞和诱导多能干细胞都不具有原始受精卵的特性,受精卵能够形成胚外组织和胚胎组织,当胚胎干细胞从小鼠或人类胚胎中收获时,这些细胞就已经被确定了身份,要么转化成为胚胎,要么转化成为胚外细胞系。

MicroRNAs是一类小型的非编码RNA分子,其能够调节基因表达;研究人员发现,名为miR-34a的MicroRNAs分子似乎能够作为一种“制动器”来抑制胚胎干细胞和诱导多能干细胞产生胚外组织,当MicroRNA被遗传性地移除后,上述两种细胞都能够扩展它们的发育决策来产生胚胎细胞类型、胎盘以及卵黄囊。研究人员发现,大约20%缺失MicroRNA的胚胎干细胞能够表现出扩展性的潜在命运,此外,这种效应或许能够在细胞培养液中维持一个月。

让研究者们非常惊奇的是,仅仅操控单一的MicroRNA就能够扩展胚胎干细胞的细胞命运决策,研究者不仅鉴别出了一种能够调节全能性干细胞的新型机制,还揭示了非编码RNAs在干细胞命运中的重要性。此外,这项研究中,研究人员还发现了miR-34a分子和小鼠机体中一类逆转录转座子之间的关联,逆转录转座子被认为是“垃圾DNA”,很多年来生物学家们推测这类转座子在机体正常发育期间似乎并没有用处,但本文研究中研究者发现逆转录转座子似乎和早期胚胎的决策制定之间也存在着密切的关联。

最后研究者Todd MacFanlan表示,目前我们面对的一个重要的问题就是是否这些逆转录转座子能够作为干细胞发育决策制定的真正驱动子,当然这还需要我们后期进一步深入研究才能够阐明。

Cell:惊人发现!细胞周期时钟控制胚胎干细胞多能性

近日,一篇刊登在国际著名杂志Cell上的研究报道中,来自新加坡A*STAR基因组研究所的研究人员通过研究首次揭示细胞周期时钟控制多能干细胞分化的分子机制,相关研究或为理解细胞分化机制,以及开发新型潜在疗法提供思路。胚胎干细胞并不能分化为特殊类型的细胞,当其出于多能性状态时才可以,细胞周期分为四个阶段:G1、S、G2及M期,此前有研究发现胚胎干细胞的细胞分化尽在G1期才开始,而由于G1期的特性才会

NCB:靶向代谢酶可维持胚胎干细胞原始态

                最近一项研究表明,细胞代谢产物改变能够调节生命最早期阶段的胚胎干细胞发育。这项研究将帮助科学家提高应用胚胎干细胞获得新组织和新器官的能力,同时也会促进不孕不育以及癌症等常见病治疗方法的开发。   相关研究结果发表在国际学术期刊Nature Cell Biology

Cell:诱导人胚胎干细胞快速和高效地产生12种高纯度的中胚层细胞群体

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绘制出快速地和高效地指导人胚胎干细胞变成骨细胞、心肌细胞和软骨细胞等12种细胞中任何一种纯的细胞群体所必需的生物学信号和化学信号。相关研究结果发表在2016年7月14日那期Cell期刊上,论文标题为“Mapping the Pairwise Choices Leading from Pluripotency to Human Bone, He

JAAOS:评述用于治疗脊髓损伤的干细胞益处

干细胞疗法是一种快速演变的大有希望的脊髓损伤治疗方法。根据一篇新的发表在Journal of the American Academy of Orthopedic Surgeons(JAAOS)期刊上标题为“The Use of Cell Transplantation in Spinal Cord Injuries”的文献综述,不同类型的干细胞在恢复受损脊髓功能上存在差异,然而目前仍然没有

日本科学家小保方晴子是不是被冤枉了?

瑞士洛桑联邦理工学院(EPFL)的科学家开发出了一种方法,可以通过“挤压”细胞使其转变成为干细胞,该方法为大规模生产干细胞用于医学目的提供了新的思路,相关研究发表于国际杂志2016年1月11日的《自然材料》(Nature Materials)上。这条近日发布的科学新闻可能不会引起人们太多的关注,因为科学的深奥让公众一般对其敬而远之,而且有关干细胞研究的成果或结果可谓过江之鲫,没法吸引眼球。不过,如
