WFDC2 and SLPI do not co-localise in major and minor glands. The expression of WFDC2 (A, D) was directly compared with that of the related 2-WAP domain containing protein SLPI (B, E) and the mucous cell marker SPLUNC1 (C, F) in multiple glandular tissues as described in the materials and methods. Sections shown are submandibular gland (A-C) and bronchial sub-mucosal glands (D-F). The original magnification of the images was ×200.
