Stimulation of submucosal glands fluid secretion of mouse trachea by osthole. (A) Bright field micrographs of expanding fluid droplets secreted from single submucosal glands. a, saline; b, osthole; c, osthole plus CFTRinh-172; d, pilocarpine; e, pilocarpine plus CFTRinh-172. (B) Linear volume increase of gland droplets (mean ± SE, n = 12) with time after stimulation.
