Cytoskeletal networks form complex intracellular structures. Here we investigate a minimal model for filament-motor mixtures in which motors act as depolymerases and thereby regulate filament length. Combining agent-based simulations and hydrodynamic equations, we show that resource-limited length regulation drives the formation of filament clusters despite the absence of mechanical interactions between filaments. Even though the orientation of individual remains fixed, collective filament orientation emerges in the clusters, aligned orthogonal to their interfaces.

长度调节驱动灯丝-马达混合物中的自组织

细胞骨架网络形成复杂的细胞内结构。在这里，我们研究了灯丝-马达混合物的最小模型，其中马达充当解聚酶，从而调节灯丝长度。结合基于代理的模拟和流体动力学方程，我们表明，尽管细丝之间没有机械相互作用，但资源有限的长度调节驱动了细丝簇的形成。即使个体的方向保持固定，集群中也会出现集体细丝方向，与它们的界面正交对齐。
