摘要 目的研究卵巢神经内分泌细胞(neuroendocrine cells,NECs)在浆液性囊腺癌的"胚性重演",探讨其生物学意义。方法采用免疫组化SP法检测嗜铬素A(CgA)、突触素(Syn)在40例卵巢浆液性囊腺癌、20例正常卵巢和6例胎儿卵巢中的表达,图像定量分析其表达情况;应用透射电子显微镜分别观察三者组织中NECs的超微结构特征。结果卵巢浆液性囊腺癌组织NECs分布范围及染色强度高于胎儿卵巢,均明显高于正常卵巢组(P<0.05),随组织分化程度下降,NECs的表达增强,其超微结构特征亦与胎儿卵巢有相似之处。结论 NECs在卵巢浆液性囊腺癌和胎儿卵巢有相似的细胞结构特征,提示它们在胎儿卵巢发育和浆液性囊腺癌组织发生中可能存在相同的调节因素。
