Figure 5. Amounts of lactoferrin protein secreted into the medium from cultured lacrimal gland (LG) acinar cells were analyzed by immunoblotting. Cells were treated with PACAP-27 and VIP at increasing concentrations. Below: The graph shows density of lactoferrin protein bands, expressed as mean±SEM (n=6). *p<0.05 is relative to vehicle with Dunnett’s t test.
