Figure 7. Neonatal co-infection does not elicit hyperreactivity in vitro in lung slices.

(A) Representative phase-contrast images and (B) time-course trace of an intrapumonary airway in mouse precision cut lung slice contracting to increasing concentrations of perfused methacholine (MCh). Time-course trace and (C) grouped data are expressed as % inital airway lumen area as calculated following greyscale analysis of airway lumen size (n = 3−5).
