Apoptosis of wound fibroblasts induced by oxidative stress.

abstract：PURPOSE:This study aimed to investigate differential cell responses of alveolar epithelial cells (AECs) after treatments with lipopolysaccharide (LPS) and hydrogen peroxide (H2O2) to mimic the exposure to inflammation and oxidative stress and the mechanisms of a double-hit model of apoptosis. MATERIALS AND METHODS:AEC...
