神经发育的一个主要标志是细胞核在神经上皮的顶面和底面之间的振荡运动,这是动力学核间迁移(IKNM)的过程。在这里,我们采用长期的,快速的光片和双光子成像的斑马鱼视网膜在早期发展,揭示的物理过程中,管理IKNM核的行为。这些图像可以捕捉到许多紧密堆积的细胞核在早期视网膜发生过程中的核运动和分裂的可靠轨迹。然后,这些轨道被用来创建和测试视网膜IKNM的理论作为一个扩散的过程中产生的核浓度梯度在顶端表面添加新的核。分析揭示了核的迁移动力学的顶端表面的核包装的作用,提供了一个强大的定量解释整个视网膜的核的分布,并可能有影响,在这个系统中的随机命运选择。
A major hallmark of neural development is the oscillatory movement of nuclei between the apical and basal surfaces of the neuroepithelium during the process of interkinetic nuclear migration (IKNM). Here, we employ long-term, rapid lightsheet and two-photon imaging of zebrafish retinasduring early development to uncover the physical processes that govern the behavior of nuclei during IKNM. These images allow the capture of reliable tracks of nuclear movements and division during early retinogenesis for many tightly packed nuclei. These tracks are then used to create and test a theory of retinal IKNM as a diffusive process across a nuclear concentration gradient generated by the addition of new nuclei at the apical surface. The analysis reveals the role of nuclear packing at the apical surface on the migration dynamics of nuclei, provides a robust quantitative explanation for the distribution of nuclei across the retina, and may have implications for stochastic fate choice in this system.
