Abstract
Oxidative stress has been implicated in a variety of diseases of the eye. In several other tissues, keratinocyte growth factor (KGF) has been shown to prevent negative cellular changes associated with oxidative insult, such as permeability increases and nuclear DNA damage. In this study, we looked at whether KGF provided these same protective effects to cultured human retinal pigmented epithelial (RPE) cells (ARPE-19).
