细胞的集体运动:从实验到模型

Collective motion of cells: from experiments to models

Elod Mehes, Tamas Vicsek

摘要:

生物的群集运动是近年来被广泛研究的生命系统最常见和最壮观的表现之一。已经确立了一些一般原则。细胞水平上的相互作用与动物个体之间的相互作用有很大的不同,因此对细胞集体运动的研究可能揭示一些特殊的重要特征,本文对此进行了综述。除了从快速增长的相关文献中提出最吸引人的结果外,我们还对新兴的图片进行了批判性的讨论,并总结了我们目前在细胞水平上对集体运动的理解。细胞的集体运动在许多实验和现实生活中起着至关重要的作用。在大多数情况下,协调运动是给定现象的有帮助的方面,并且导致使相关过程更有效(例如,胚胎发生或伤口愈合),而在肿瘤细胞侵入的情况下,它似乎加速疾病的进展。在这些机制中,细胞既要能动,又要相互粘附,粘附特征是这种集体行为最具特异性的特征。这篇评论的中心目的之一是提出相关的实验观察,并根据一些基本的计算模型来处理它们,以便在定量水平上对这些现象进行解释。

英文摘要:

Swarming or collective motion of living entities is one of the most common and spectacular manifestations of living systems having been extensively studied in recent years. A number of general principles have been established. The interactions at the level of cells are quite different from those among individual animals therefore the study of collective motion of cells is likely to reveal some specific important features which are overviewed in this paper. In addition to presenting the most appealing results from the quickly growing related literature we also deliver a critical discussion of the emerging picture and summarize our present understanding of collective motion at the cellular level. Collective motion of cells plays an essential role in a number of experimental and real-life situations. In most cases the coordinated motion is a helpful aspect of the given phenomenon and results in making a related process more efficient (e.g., embryogenesis or wound healing), while in the case of tumor cell invasion it appears to speed up the progression of the disease. In these mechanisms cells both have to be motile and adhere to one another, the adherence feature being the most specific to this sort of collective behavior. One of the central aims of this review is both presenting the related experimental observations and treating them in the light of a few basic computational models so as to make an interpretation of the phenomena at a quantitative level as well.
