Expressioni

Tissue specificityi

Selectively expressed in cornea of adult where it is detected in keratocytes but not in scleral cells. In embryo, first detected in periocular mesenchymal cells migrating toward developing cornea on E13.5; expression gradually restricted to corneal stromal cells on E14.5 to E18.5. Detected in scleral cells of E15.5 but not in E18.5 embryos.
