title: Production of proteases type plasminogen activator and their inhibitor in cornea.
abstract: Corneal epithelial cells secrete tissue plasminogen activator (t-PA), urokinase type plasminogen activator (u-PA) and their inhibitor (PAI), whereas these cell types in other tissues are known to secrete only u-PA hitherto. Endothelial cells in the cornea produce mostly u-PA and only small amounts of t-PA and PAI which remain confined in the cellular compartment contrary to the situation in the vascular endothelial cells where they are liberated into the circulation in the order PAI greater than t-PA greater than U-PA. These unique features of activator/inhibitor secretion and production may play an important role in the remodeling of the corneal matrix.
