Abstract:
Objective To investigate the differential expression of synaptophysin(SYN)in the developing rat cochlea,to analyze the relationship between the expression of SYN and auditory functional development,and to explore the source of the adenosine triphosphate(ATP)in the cochlea.Methods The immunofluorescence was applied to observe the differential expression of SYN in the cochlea of SD rats on different days(p1,p5,p10,p14 and p28)after parturition.Results No significant stain was observed in the Kolliker organ or the Corti's organ of P1,P5 and the top turn of the cochlea in P10.The SYN expression was turned on the outer spiral bundle,the inner spiral bundle,and the medial wall of the Deiters' cell of the cochlea in P14,P28 and the second or the third turn of Corti's organ of P10.All the spiral ganglion neurons(SGN)were stained in different aged cochlea.Conclusion The expression of SYN was different during development of rat cochlea.This difference was in favor of the configuration constructed between nerve endings and target cells.It also played a key role in the formation of correct auditory coding during auditory system development.The hair cells and the supporting cells,possible the source of ATP in the cochlea,contained ATP that maybe existed in a non-vesicular form or specific staining of non-SYN.
