High-power micrograph of Rhbg localization in bronchiolar epithelial cells. High-power micrograph of Rhbg immunoreactivity both confirms basolateral expression and, using differential interference contrast (DIC) optics, demonstrates that ciliated cells (“*”) do not express detectable Rhbg immunoreactivity, whereas nonciliated cells (arrows) demonstrate easily detectable basolateral Rhbg.
