Regeneration of lateral line and inner ear vestibular cells.

摘要: Labelling experiments with [3H]thymidine demonstrate a continuous production of cells in the mechanoreceptive lateral line organs eel (Anguilla anguilla) and butterfly fish (Pantodon buchholzi) as well electroreceptive ampullary organ transparent catfish (Kryptopterus bicirrhus). Shortly after injection many are labelled middle basal parts sensory few days' survival also labelled. The vestibular selected species fishes, amphibians, reptiles birds show cells. In budgerigar (Melopsittacus undulatus) found layer epithelium hours [3H]thymidine. A days non-calyceal hair After one month calyceal Similar bat Pipistrellus nathusii normal gentamicin-treated mice (Mus musculus) no inner ear epithelia. epithelia non-mammalian vertebrates all contain small number dark characteristics apoptotic Macrophages inclusions some cells, thought to be remnants occasionally seen. Fixation at different osmolarities has little effect on It is suggested that continually produced replace dying
