The planar cell polarity (PCP) pathway is best known for its role in polarizing epithelial cells within the plane of a tissue but it also plays a role in a range of cell migration events during development. The mechanism by which the PCP pathway polarizes stationary epithelial cells is well characterized, but how PCP signaling functions to regulate more dynamic cell behaviors during directed cell migration is much less understood. Here, we review recent discoveries regarding the localization of PCP proteins in migrating cells and their impact on the cell biology of collective and individual cell migratory behaviors.
平面细胞极性(PCP)通路最为人所知的是其在组织平面内使上皮细胞极化的作用,但它在发育过程中的一系列细胞迁移事件中也发挥作用。PCP通路使静止上皮细胞极化的机制已得到充分表征,但PCP信号在定向细胞迁移过程中如何调节更动态的细胞行为却知之甚少。在这里,我们综述了关于PCP蛋白在迁移细胞中的定位及其对集体和单个细胞迁移行为的细胞生物学影响的最新发现。
