Figure 1.

The β8 integrin subunit mRNA is highly abundant in airway fragments in culture. a: The relative abundance of the β8, β6, and β1 integrin subunit transcripts was compared using nested primers to amplify preamplified oligo-dt-primed cDNA from airway fragments after 3 days in culture (n = 8). Shown are the relative transcript numbers for each integrin subunit from each fragment. Bars indicate the median value. Each circle, square, or diamond represents a single fragment. b: The same data shown in a is depicted in bar graph form to show SE. *, P < 0.001.
