Figure 12. Cells obtained by brushing monkey nasal epithelium infected with Ad2/BGal-l. 
Top panel shows cells stained with Wright stain (630X magnification); ciliated epithelial cells 
are readily apparent. Field also contains a neutrophil. Although this was the only neutrophil on 
the entire slide, it is included to show the ability of nasal brushings to detect inflammatory cells. 
Bottom panel shows cells stained with X-Gal (400X magnification).
