Popis: | The nasal cavity of turtles is composed of the upper and lower chambers, lined by the upper and lower chamber epithelia, respectively. In many turtles including the Reeve's turtle Mauremys reevesii, the upper chamber epithelium contains ciliated olfactory receptor neurons (ORNs) and the lower chamber epithelium contains microvillous ORNs. However, in the olfactory organ of the Chinese soft-shelled turtle Pelodiscus sinensis, both the upper and lower chamber epithelia contain ciliated ORNs. In the present study, we immunohistochemically examined the developmental process of olfactory organs in soft-shelled turtle and the Reeve's turtle to clarify the developmental origins of the lower chamber epithelium in these turtles. Obtained data indicate that olfactory organs of these turtles have identical origin and follow similar process of development, suggesting that, in the lower chamber epithelium of the nasal cavity, ciliated ORNs differentiate in soft-shelled turtle whereas microvillous ORNs differentiate in the Reeve's turtle. |
