From: Cigarette smoke exposure facilitates allergic sensitization in mice
Eosinophils and goblet cells in the airway wall of mice exposed to phosphate buffered saline (PBS) or ovalbumin (OVA) combined with air or cigarette smoke (SM) for three weeks. A. Congo red staining for eosinophils in OVA- and air-exposed mice. B. Congo red staining for eosinophils in simultaneously OVA- and smoke-exposed mice. The arrows are indicating eosinophils. C. Periodic acid-Schiff staining for goblet cells in OVA- and air-exposed mice. D. Periodic acid-Schiff staining for goblet cells in simultaneously OVA- and smoke-exposed mice.
