Cadherin expression in the inner ear of developing zebrafish

Gene Expr Patterns. 2003 Jun;3(3):337-9. doi: 10.1016/s1567-133x(03)00030-9.

Abstract

Cadherins are cell adhesion molecules that have been implicated in development of a variety of organs including the ear. In this study we analyzed expression patterns of three zebrafish cadherins (Cadherin-2, -4, and -11) in the embryonic and larval zebrafish inner ear using both in situ hybridization and immunocytochemical methods. All three Cadherins exhibit distinct spatiotemporal patterns of expression during otic vesicle morphogenesis. Cadherin-2 and Cadherin-4 proteins and their respective mRNAs were detected mainly in the sensory patches and the statoacoustic ganglion (SAg), respectively. In contrast, cadherin-11mRNA was widely expressed earlier in the otic placode, and later became restricted to a subset of cells in the inner ear, including hair cells.
