在细胞的复杂环境之外重建细胞行为允许在简化和受控的环境中研究生物过程。然而,从细胞到试管的飞跃不可避免地带来了删除太多背景的风险,因此牺牲了指导系统行为的重要生物化学,机械或几何约束。为了应对这一挑战,重构实验最近开始不仅关注包含正确的分子,而且还关注忠实地再现细胞内存在的约束。通过设置适当的生物边界条件,这些实验揭示了细胞环境中的尺寸约束如何指导生物过程。
Reconstituting cellular behavior outside the complex environment of the cell allows the study of biological processes in simplified and controlled settings. Making the leap from cells to test tubes, however, carries the inevitable risk of removing too much context and therefore sacrificing the important biochemical, mechanical, or geometrical constraints that guide the system's behavior. In response to this challenge, reconstitution experiments have recently begun to focus not only on including the right molecules but also on faithfully recapitulating the constraints that are present within a cell. By setting the appropriate biological boundary conditions, these experiments are uncovering how dimensional constraints within the cellular environment guide biological processes.
