不同的动物细胞类型有不同的特征大小。一个特定的细胞大小是如何由分化程序和生理学决定的,这仍然是细胞生物学中的一个基本未知数。在这篇综述中,我们探索了单个细胞自主感知并指定自己的大小的证据。我们讨论了尺寸感知和尺寸指定的可能机制。最后,我们探讨了大小控制的生理学意义。为什么特定的细胞类型保持特定的大小很重要?我们通过审查当前的文献来提出这些问题,并提出我们预计将在未来几年指导这一领域的问题。
Different animal cell types have distinctive and characteristic sizes. How a particular cell size is specified by differentiation programs and physiology remains one of the fundamental unknowns in cell biology. In this review we explore the evidence that individual cells autonomously sense and specify their own size. We discuss possible mechanisms by which size sensing and size specification may take place. Finally, we explore the physiological implications of size control. Why is it important that particular cell types maintain a particular size? We develop these questions by examination of current literature and pose the questions that we anticipate will guide this field in the upcoming years.
