From: An ovine tracheal explant culture model for allergic airway inflammation
Immunostaining for mast cells and eosinophils in tracheal explants. Mast cell (tryptase+) staining in (A) control and (B) allergic tissues, and eosinophil (galectin-14+) staining in (C) control and (D) allergic tracheal explants. Note the increased number of immunopositive mast cells and eosinophils in the allergic (indicated by arrows in B and D) compared to the control tracheal explants (original magnification ×200).
