Corneal endothelial cells (CECs) have limited regeneration capacity in primates while display a potent restorative capability in some species such as rodents after wounding. The mechanism which determines the regenerative capability of CECs remains poorly understood. Here, we identified that the Hippo pathway was inhibited and the downstream effector YAP was activated during CEC wound healing in rabbits. Knockdown of Yap1 and pharmacological inhibition of YAP suppressed CECs wound healing in rodents in both in vitro and in vivo models. XMU-MP-1, a specific small molecular inhibitor for Hippo pathway, could promote the corneal endothelial regeneration in rodents and corneal endothelial proliferation in cultured primate CECs, as well as in vivo non-human primate CEC wounding model. These findings suggest that Hippo pathway serves as a conserved signal to regulate corneal endothelial regeneration among various species, providing a novel target for non-invasive treatment of corneal endothelium decompensation. One Sentence SummaryThe Hippo pathway regulates corneal endothelial regeneration across species, revealing a therapeutic strategy for corneal endothelial decompensation.
