Mucin Gene Expression in Reflux Laryngeal Mucosa: Histological and In Situ Hybridization Observations

Figure 1

Mucin gene expression in normal laryngeal mucosa. In situ hybridization photographs of the expression of MUC3 and 4 in vocal cords mucosa ((a) and (b), resp.) and MUC5AC in laryngeal ventricles mucosa (c). Sections were lightly counterstained in Harris’ hematoxylin and then immersed in Scott’s modified tap water (bluing reagent). Arrows indicate areas of mucin gene expression. Magnification 200X.
