Vitronectin expression in human bronchial tissues.

<p>Expression in submucosal glands (<b>a</b>), and in respiratory surface epithelium (<b>b</b>). The measurements included 7 healthy controls (HC), 6 asthmatic and 4 COPD subjects. For submucosal glands 42 control, 41 asthmatic and 19 COPD acinar structures were evaluated; whereas for respiratory surface epithelium 37 control, 32 asthmatic and 16 COPD tissue structures were assessed. GEA, glandular epithelial area; SEA, surface epithelium area.
