Mucin Production and Mucous Cell Metaplasia in Otitis Media
Figure 3
Mucins MUC5AC and MUC5B are two predominant mucins in the middle ear and Eustachian tube areas. (a) MUC5AC is typically expressed in the epithelial cells of the Eustachian tube. (b) MUC5B is predominantly expressed in the mucous cells of submucosal glands. (c) Control for in situ hybridization in (a) and (b). Note: Black dots indicate the mRNA transcripts for MUC5AC or MUC5B.
