| Abstract: |
| 【Objective】 The research was done in order to study the distribution properties of diffused neuroendocrine system cells in ovary.【Method】 Indirect immunofluorescence technique was used to detect the expressiom of diffuse neuroendocrine cells common markers S100 protein and neuron specific enolase in mouse ovary during different physiological periods.【Result】 The results showed that S100 protein and NSE expression existed in the cytoplasm of theca layer surrounding secondary follicle and antral follicle in estrus cycle and in the cytoplasm of theca layer of antral follicle in gestational period and also in the corepus luteum.Those cells were distributed single or congregate.They were rotund,oval and triangle.Some cells had obvious neurites.【Conclusion】 It could be inferred that DNES cells exist in the mouse ovary.S100 protein and NSE exert different roles in the process of ovarian follicular development,and some cells develop DNES cells during ovary development. |
