Wnt-Frizzled/planar cell polarity (PCP) signaling establishes cell orientation within the epithelial plane, but whether Wnts are instructive or permissive is debated. Reporting in Developmental Cell, Minegishi et al. (2017) uncover an instructive link from Wnt5a/b gradients to PCP-factor-regulated polarized cilia positioning that is essential to mouse embryo left-right asymmetry establishment.
Wnt-Frizzled/平面细胞极性(PCP)信号通路确立上皮平面内的细胞方向,但Wnts是起指导性作用还是允许性作用仍存在争议。峰岸等人(2017年)在《发育细胞》杂志上发表报告,揭示了从Wnt5a/b梯度到PCP因子调节的极化纤毛定位之间的指导性联系,这对于小鼠胚胎左右不对称的建立至关重要。
