Planar cell polarity signaling governs a wide array of polarized cell behaviors in animals. Recent reports now show that PCP signaling is essential for the directional beating of motile cilia. Interestingly, PCP signaling acts in a variety of ciliated cell types that use motile cilia to generate directional fluid flow in very different ways. This review will synthesize these recent papers and place them in context with previous studies of PCP signaling in polarized cellular morphogenesis and collective cell movement.
平面细胞极性信号转导控制着动物中广泛的极化细胞行为。最近的报告显示,PCP 信号对于运动纤毛的定向摆动是必不可少的。有趣的是,PCP 信号在多种纤毛细胞类型中发挥作用,这些细胞类型通过运动纤毛以非常不同的方式产生定向的流体流动。这篇综述将综合这些最新的论文,并将它们置于 PCP 信号在极化细胞形态发生和细胞集体运动中的先前研究背景下。
