尖端生长细胞有一种特殊的生活方式，其特征如下：(1)细胞单向生长，形成圆柱管；(2)尖端生长细胞能够穿透其生长环境，因此必须承受相当大的外力；(3)尖端生长细胞的生长速度是生物系统中最快的之一。因此，尖端生长细胞似乎是一个非常适合研究生长过程的系统。细胞骨架在细胞生长中起着重要的作用，这就是为什么尖端生长细胞为这方面的研究提供了一个很好的模型系统。细胞骨架系统包括肌动蛋白细丝和微管等结构元素，以及连接这些元素、控制其形态或负责以结构元素为轨迹的运输过程的蛋白质。不同类型的尖端生长细胞中细胞骨架的共同方面以及结构和功能上的差异揭示了控制细胞骨架和细胞生长之间关系的一般原理。
Tip-growing cells have a particular lifestyle that is characterized by the following features: (1) the cells grow in one direction, forming a cylindrical tube; (2) tip-growing cells are able to penetrate their growth environment, thus having to withstand considerable external forces; (3) the growth velocity of tip-growing cells is among the fastest in biological systems. Tip-growing cells therefore appear to be a system well suited to investigating growth processes. The cytoskeleton plays an important role in cell growth in general, which is why tip-growing cells provide an excellent model system for studying this aspect. The cytoskeletal system comprises structural elements, such as actin filaments and microtubules, as well as proteins that link these elements, control their configuration or are responsible for transport processes using the structural elements as tracks. Common aspects as well as differences in configuration and function of the cytoskeleton in various types of tip-growing cells reveal the general principles that govern the relationship between the cytoskeleton and cell growth.
