Regarded as a complex biological process, lens development involves a range of signal molecules and their crosstalk networks. Recently,the role of planar cell polarity(PCP)signaling pathway in lens development has attracted increasing attention. It has been reported that PCP is critical for lens morphology and transparency maintaining. The studies performed on PCP serve to provide guidelines on how to optimize the morphology of regenerated lens. This is thought as presenting an effective therapy for infant cataract from a clinical perspective. This article will give a comprehensive review of the role of PCP signaling pathways in the lens development.
