[Distribution of beta-actin within hair cells in the chick: comparatived with those in the guinea pig cochleae].
OBJECTIVE
To study the distribution of beta-actin in the chicken and guinea pig cochlea hair cells.


METHODS
beta-actin immunoreactivity was observed by immunohistochemistry.


RESULTS
beta-actin was located in stereocilia of hair cells and cytoplasm of marginal epithelium cells which tectorial membrane attached in basilar papilla; In the corti's organ beta-actin was present in three row outer hair cells cytoplasm and the phalangeal process and cytoplasm of the tunnel cells.


CONCLUSIONS
There is a common cytoskeletal protein beta-actin in the chick and guinea pig cochleae, but the distribution of beta-actin in two species are different significantly.
