WebApr 12, 2024 · Epithelial cells are the building blocks of epithelial tissue. Like every other cell, they are surrounded by cellular membranes. Epithelial cell membranes have three regions (domains) different in structure and function; apical, lateral and basal. This feature is called membrane polarity. Polarity Plasma membrane Plasmalemma 1/2 WebRotenone, a mitochondrial complex I inhibitor, partially abrogated the stretch-induced generation of O2- after 2 h CMS in 16HBE cells. NADPH oxidase activity was increased after 2 h of CMS, contributing to the production of O2-. Increased ROS production in lung epithelial cells in response to elevated stretch may contribute to the onset of VILI.
