摘　　要：目的探讨人脐带间充质干细胞(hUC-MSCs)对大鼠子宫内膜异位症(EMs)病灶神经纤维的影响。方法hUC-MSCs从人新鲜脐带组织中分离和培养,并经过流式细胞仪鉴定。将体质量180～210 g成年雌性Wistar大鼠,通过手术成功被诱导为EMs模型。将模型鼠随机分为治疗组和对照组,各12只。2周后治疗组接受含有hUC-MSCs的生理盐水尾静脉注射两周,1次/周,对照组接受相同体积和次数的生理盐水注射。4周后子宫内膜异位病灶被收集。标本被切片和用抗神经丝蛋白(NF)和神经生长相关蛋白-43(GAP-43)抗体进行免疫组化。结果与对照组相比,治疗组的NF平均光密度值明显低于对照组(P<0.01);GAP-43的平均光密度值与对照组相比也明显降低(P<0.01)。结论 hUC-MSCs能够降低EMs病灶的神经纤维密度值。Objective To investigate the influence of human umbilical cord mesenchymal stem cells （hUC-MSCs） on nerve fibers in the lesions of rat models of endometriosis （EMs）. Methods hUC-MSCs were isolated and cultured from fresh human umbilical cord, then identified by flow cytometry. Adult female Wistar rats, weighing 180-210g, were surgically induced EMs. Thereafter the EMs rat models were randomly divided into two groups （12 rats each）, namely the treatment group and the control group. Two weeks later, the treatment group received hUCMSCs by injection of normal saline into the tail vein once a week for two weeks. Meanwhile, the control group only received the same volume of normal saline. EMs lesions were collected four weeks later. The specimens were sectioned and stained immunohistochemically with antibodies against Neurofilament （NF） and Growth Associated Protein 43 （GAP-43）. Results Compared to that of the control group, the mean density of NF-immunoreactive nerve fibres of the treatment group was remarkably lower（P〈0.01）. Besides, the mean density of nerve fibres stained with GAP-43 was also much lower in the treatment group in comparison with that of the control group（P〈 0.01）. Conclusion MSCs from human umbilical cord could reduce the nervefiber density of EMs lesions.
