长期以来,理论家们一直在推测驱动定向和自发细胞极化的机制。最近,实验学家发现了许多极化机制,使这些模型能够直接测试。在这个过程中,他们已经证明了这些模型的解释和预测价值,同时发现了它们目前无法解释的额外复杂性。在这篇综述中,我们讨论了一些关于细胞极化的主要理论,并强调了数学和实验生物学的交叉如何在芽殖酵母和真核生物趋化性的情况下对这些机制产生了新的见解。
Theorists have long speculated on the mechanisms driving directed and spontaneous cell polarization. Recently, experimentalists have uncovered many of the mechanisms underlying polarization, enabling these models to be directly tested. In the process, they have demonstrated the explanatory and predictive value of these models and, at the same time, uncovered additional complexities not currently explained by them. In this review, we discuss some of main theories regarding cell polarization and highlight how the intersection of mathematical and experimental biology has yielded new insights into these mechanisms in the case of budding yeast and eukaryotic chemotaxis.
