发展依赖于一系列精心策划的细胞命运变化。虽然对命运转变的研究通常集中在基因调控网络的变化上,但大多数转变也与细胞形状和细胞行为的变化有关。在这里,我们研究了小鼠胚胎干细胞(ES)在其第一个发育命运转变过程中迁移行为的变化,即退出ES细胞状态。我们发现,幼稚的多能ES细胞不能有效地在二维基质上迁移,但当被限制时,它能够以变形虫的方式迁移。退出ES细胞状态,典型的特征是细胞扩散增强,与2D基质上限制和获得间充质样迁移的减少相关。有趣的是,ES细胞受限的阿米巴样游走强烈依赖于肌球蛋白IIA,而不是肌球蛋白IIB。相反,退出ES细胞状态的细胞间充质样迁移不依赖于肌球蛋白运动活性,而依赖于Arp2/3复合体的活性。综上所述,我们的数据表明,在细胞分化的早期,细胞经历了肌动蛋白细胞骨架调控的转换,导致了从阿米巴样向间充质样迁移的转变。总结声明幼小的小鼠胚胎干细胞在限制条件下表现出阿米巴样迁移,但当它们离开ES细胞状态时,会切换到间充质样迁移。
Development relies on a series of precisely orchestrated cell fate changes. While studies of fate transitions often focus on changes in gene regulatory networks, most transitions are also associated with changes in cell shape and cell behaviour. Here, we investigate changes in migratory behaviour in mouse embryonic stem (ES) cells during their first developmental fate transition, exit from ES cell state. We show that naïve pluripotent ES cells cannot efficiently migrate on 2-dimensional substrates but are able to migrate in an amoeboid fashion when placed in confinement. Exit from ES cell state, typically characterised by enhanced cell spreading, is associated with decreased migration in confinement and acquisition of mesenchymal-like migration on 2D substrates. Interestingly, confined, amoeboid-like migration of ES cells strongly depends on Myosin IIA, but not Myosin IIB. In contrast mesenchymal-like migration of cells exiting the ES cell state does not depend on Myosin motor activity but relies on the activity of the Arp2/3 complex. Together, our data suggest that during early differentiation, cells undergo a switch in the regulation of the actin cytoskeleton, leading to a transition from amoeboid-to mesenchymal-like migration.Summary statementNaïve mouse embryonic stem cells display amoeboid-like migration in confinement, but switch to mesenchymal-like migration as they exit the ES cell state.
