Figure 2. Immunofluorescence staining of VPAC2 receptors in lacrimal gland tissues of WT and CFTR mice. VPAC2 was observed on the basolateral surface of duct (d) and acinar (ac) cells. There were no significant differences between the wild-type (WT) and cystic fibrosis transmembrane conductance regulator (CFTR) knockout (KO) samples. Hoechst dye was used to stain nuclei blue.
