细胞的大小和生长

On size and growth of cells

Arezki Boudaoud

摘要:

了解生长如何诱导形态是一个长期存在的生物学问题。许多研究集中在植物细胞、真菌或细菌的形状上。其他一些人已经表明细菌壁和植物组织的机械性质在斑图形成中的重要性。在这里,我勾勒出一个简单的细胞生长的物理图像。这项研究的重点是有墙的孤立细胞。它们被建模为含有液体的薄弹性壳,这种压力驱动细菌或植物细胞的生长。需要机械平衡导致典型的细胞大小的估计,在定量协议与编译的数据,包括细菌,耳蜗外毛,真菌,酵母,根毛和巨噬细胞。

英文摘要:

Understanding how growth induces form is a longstanding biological question. Many studies concentrated on the shapes of plant cells, fungi or bacteria. Some others have shown the importance of the mechanical properties of bacterial walls and plant tissues in pattern formation. Here I sketch a simple physical picture of cell growth. The study is focussed on isolated cells that have walls. They are modeled as thin elastic shells containing a liquid, which pressure drives the growth as generally admitted for bacteria or plant cells. Requiring mechanical equilibrium leads to estimations of typical cell sizes, in quantitative agreement with compiled data including bacteria, cochlear outer hair, fungi, yeast, root hair and giant alga cells.
