Reconstituted Human Upper Airway Epithelium as 3-D In Vitro Model for Nasal Polyposis
Figure 2
Ultrastructural study in ALI cultures from both nasal polyp and control nasal mucosa at different days by transmission electron microscopy.
At day 0 (left column), representative images are showing desmosomes (arrowheads), interdigitations (asteriks). At day 14 (centre column), ciliated (C), goblet (G) and basal (B) cells. At day 28 (right column), longitudinal sections of motile cilia (upper) and secretory granules of a goblet cell (lower).
