The embryonic development of the inner ear of the guinea pig was investigated by immunohistological methods. The 33-35th, 37-39th, and 44-46th gestational day guinea pigs, which had been administrated bromodeoxyuridine (BrdU) in their mother, was collected.
In every gestational day BrdU labeling cells were not detected in the epitherial layer facing the endolymph. This result and ultramorphological study show that these epitherial layer finished the stage of the cell division and was in the differentiation stage.
