From: Temporal differentiation of bovine airway epithelial cells grown at an air-liquid interface
Ultra-structural comparison of goblet cells and paracellular spaces in ex vivo bronchial epithelium and differentiated BBECs using TEM. Ex vivo bronchial epithelium and day 21 post-ALI BBEC cultures were fixed and resin embedded, and ultrathin sections were cut and contrast stained. Images highlight (A) goblet cells (arrows) containing numerous secretory vesicles (arrowheads) and (B) paracellular spaces (arrows) containing membranous interdigitations (arrowheads).
