Effect of BAK exposure and PBS-soaked lenses on cell integrin expression in a curved, stratified culture of corneal epithelial cells after 6 and 24 hours.

Following exposure to stimuli, the surface of the stratified cultures were gently washed and this supernatant was collected and processed. CD49c and CD29 expression was measured by flow cytometry and is expressed as a ratio relative to expression on cells incubated with no lens or BAK (control). BA PBS: PBS-soaked balafilcon A lens.
n = 3–5.
*significantly different from 6 hour value, p<0.05.
