The superfamily of serine proteinase inhibitors (serpins) is involved in a number of fundamental biological processes such as blood coagulation, complement activation, fibrinolysis, angiogenesis, inflammation and tumor suppression and are expressed in a cell-specific manner [1]. The pigment epithelium-derived factor (PEDF) is a 50-kD serpin that lacks inhibitory properties against either serine or cysteine proteinases [2]. PEDF was first identified in 1987 by Tombran-Tink and Johnson in conditioned medium from foetal human retinal pigment epithelium cell cultures (published in 1991 [3]). PEDF has been shown
