摘要 目的比较经尾静脉、肝实质内及胰腺被膜下输注的人脐带间充质干细胞(h UCMSCs)在糖尿病大鼠胰腺组织中的移植定植效果,探讨h UCMSCs移植治疗糖尿病的最佳途径。方法取采用一次性腹腔注射链脲佐菌素制备1型糖尿病(T1DM)大鼠42只,随机分为模型尾静脉组、模型肝实质组、模型胰腺被膜组各6只,观察尾静脉组、观察肝实质组、观察胰腺被膜组各8只。观察尾静脉组、观察肝实质组、观察胰腺被膜组分别经尾静脉、肝实质内、胰腺被膜下途径注射h UCMSCs悬液0.4 m L,模型尾静脉组、模型肝实质组、模型胰腺被膜组分别经尾静脉、肝实质内、胰腺被膜下途径注射生理盐水0.4 m L。各组均干预4周。取各组胰腺组织,采用HE染色法观察组织病理学。采用RT-PCR法检测胰腺组织胰岛素mRNA表达,采用免疫组化法检测胰腺组织胰岛素蛋白表达。应用MAB1281蛋白示踪剂,采用免疫组化法检测胰腺组织MAB1281蛋白表达,评价h UCMSCs定植示踪情况。结果模型各组胰岛结构有不同程度破坏,胰岛细胞数量减少,部分发生空泡变性,胰岛边缘炎性细胞浸润明显;观察各组胰岛结构相对完整,炎症反应较轻。观察各组胰腺组织胰岛素mRNA及蛋白表达量均高于模型各组(P<0.05),观察胰腺被膜组胰腺组织胰岛素mRNA及蛋白表达量高于观察尾静脉组及观察肝实质组(P均<0.05)。模型各组及观察肝实质组均未见MAB1281蛋白阳性表达,观察尾静脉组及观察胰腺被膜组均可见MAB1281蛋白阳性表达区域,且观察胰腺被膜组表达高于观察尾静脉组(P<0.05)。结论三种途径移植h UCMSCs均可起不同程度的治疗作用,胰腺被膜下注射效果最佳。
