Abstract

Ocular anterior segment dysgenesis (ASD) is a failure of normal development of anterior structures of the eye, leading to lens opacification. The underlying mechanisms relating to ASD are still unclear. Previous studies have implicated transcriptional factor muscle segment homeobox 2 (Msx2) in ASD. In this study, we used Msx2 conditional knockout (CKO) mice as a model and found that Msx2 deficiency in surface ectoderm induced ASD. Loss of Msx2 function specifically affected lens development, while other eye structures were not significantly affected. Multiple lines of evidence show that calcium signaling pathways are involved in this pathogenesis. Our study demonstrates that Msx2 plays an essential role in lens development by activating a yet undetermined calcium signaling pathway.
