摘要
目的 观察原代培养的成年大鼠嗅球成鞘细胞 (OECs)Nogo(N 18)蛋白的表达 ,探讨Nogo与成鞘细胞促进神经再生作用的关系。 方法 原代培养嗅球OECs,采用免疫组织化学和双标免疫荧光细胞化学技术 ,结合激光共聚焦扫描显微镜观察。 结果 原代培养的嗅球OECs的Nogo(N 18)免疫细胞化学反应呈阳性 ,Nogo(N 18)蛋白主要分布于胞浆 ,而在胞膜及突起分布较少。 结论 嗅球 (OECs)含有Nogo A蛋白 ,提示Nogo
Objective Studying the expression of the Nogo(N\|18) in olfactory ensheathing cells(OECs) to investigate the functional relationship between Nogo and the OECs in promoting the regeneration of neurite axon. Methods The expression of the Nogo(N\|18) in the primary cultured ensheathing cells from olfactory bulb of the adult rats was studied with the method of immunocytochemical staining and double\|immunofluorescence staining examed under the confocal laser scanning microscope. Results The Nogo\|A protein was located in primary cultured ensheathing cells from the olfactory bulb.The protein was mainly distributed in the cytoplasm.The member and processes were less stained.Conclusion\ The ensheathing cells in vitro contain Nogo protein.It suggests that Nogo protein is not a depressive factor in the axon regeneration of olfactory system.\;[
