最近,随着技术力量的增加,开发系统被研究。尽管如此,仍然存在悬而未决的问题,特别是关于自组织能力及其控制。在这里,我们介绍了合成生物学工具在自上而下和自下而上方法中用于研究和构建发育系统的三个领域。首先,我们讨论合成生物学工具如何改进基于干细胞的有机体模型。其次,我们讨论了最近使用用户定义的扰动来研究模式物种中的胚胎模式的研究。第三,我们提出了在非发育系统中使用合成遗传电路进行图案形成和形态形成的“玩具模型”。最后,我们讨论了这些工具和方法如何特别有益于胚胎模型领域。在这一视角下,Morsut和Ho的目标是用合成生物学在发育系统中的最新应用来刺激干细胞和发育生物学社区:改进有机体方案,拯救模式生物中的模式突变,以及在非发育细胞系中构建“玩具模型”。最后,讨论了目前和潜在的在胚胎模型中的应用。
Recently, developmental systems are investigated with increasing technological power. Still, open questions remain, especially concerning self-organization capacity and its control. Here, we present three areas where synthetic biology tools are used in top-down and bottom-up approaches for studying and constructing developmental systems. First, we discuss how synthetic biology tools can improve stem cell-based organoid models. Second, we discuss recent studies employing user-defined perturbations to study embryonic patterning in model species. Third, we present “toy models” of patterning and morphogenesis using synthetic genetic circuits in non-developmental systems. Finally, we discuss how these tools and approaches can specifically benefit the field of embryo models. With this Perspective, Morsut and Ho aim to stimulate the stem cell and developmental biology community with the latest applications of synthetic biology for developmental systems: improvements in organoids protocol, rescue of patterning mutants in model organisms, and construction of “toy models” in non-developmental cell lines. Finally, current and potential applications in embryo models are discussed.
