小分子化合物在干细胞定向分化诱导研究中的应用

1795 人阅读发布时间:2017-05-02 14:57

干细胞即为起源细胞,它是一类具有多向分化潜能和自我复制能力的原始未分化细胞,是形成哺乳类动物的各组织器官的原始细胞。

它包括胚胎干细胞和成体干细胞。人类胚胎干细胞已能成功地在体外培养,成体干细胞可以横向分化为其他类型的细胞和组织,为干细胞的广泛应用提供了基础,为研究哺乳动物早期发育提供了很好的体外模型,为某些疾病的取代疗法提供了新的分化细胞来源,也标志着现代生物学的发展和新药物的研发进入了新的时代。干细胞的分化发育受多种内在机制和微环境因素的影响。

在适当的培养条件下,干细胞能自行分化,然而自行分化难以形成单一独特的细胞类型,无法应用于实际治疗。因此,干细胞的体外扩增和分化一般要加入生长因子、信号分子等进行遗传调控。显然,定向诱导干细胞的分化和增殖,产生特定类型的同源细胞群体需要更有效、选择性更强的细胞培养和诱导技术。随着后基因组时代的到来,一门新兴交叉科学——化学遗传学(chemicalgenetics)应运而生,利用大量的小分子化合物去研究基因和蛋白质的功能。化学遗传学继承了传统的遗传学两种不同的研究策略。正向化学遗传学采用各种小分子化合物处理细胞,诱导细胞出现表型变异,然后经过筛选,寻找小分子作用的靶标。反向化学遗传学是从基因或蛋白质与小分子化合物的相互作用研究基因或蛋白质对表型的影响,从而找到这些生物大分子的功能 

 
当今小分子化合物越来越被当作一种理解和调节干细胞的工具,这些小分子能精确地控制胚胎形成,决定细胞命运和分化过程。选择合适的小分子化合物(是否影响细胞重编程,自我更新和分化)可能影响整个项目的成败。爱必信(absin)提供一系列被广泛运用于靶向干细胞生物学中关键通路的小分子化合物。
 
小分子化合物的优势:
      ★ 渗透性好,可作用于细胞内的信号通路                                        化学来源:比生长因子更稳定、更便宜
      ★ 纯度更可控,不同批次间稳定性更好                                           通过改变浓度更易于调节使用效果
重编程
传统上的诱导多能干细胞(iPSc)是通过病毒或附加载体,外源性表达特定的多功能基因诱导而获得。这种方法诱导效率低下,而小分子化合物极大的提高了诱导效率。此外,将传统的通过载体将多功能基因整合到细胞染色体诱导而成的iPS细胞运用到临床会比较有风险,而用小分子化合物诱导的iPS使其运用到临床变得可以预期了。
维持
人诱导多能干细胞的培养难点在于单细胞的低活力,基因编程技术及细胞克隆技术的不易操作性。由于条件培养体系维持干细胞的能力有限,使得实验结果稳定性不够。小分子化合物,如CHIR99021,PD0325901, SB203580已经被用作刺激胚胎干细胞(ESc)和诱导多能干细胞(iPSc)的自我更新,增加我们对小鼠和人干细胞的多能性的理解。
分化
多能干细胞定向高效率的分化到特定的细胞需要选择性激活和抑制发育方面的信号通路。小分子可以用于鉴定哪一条信号通路是分化必需的,也是一种控制细胞分化的有效工具,而且在很多情况下可以取代更加昂贵的生长因子。
