摘要
目的:探讨大鼠甲状旁腺细胞的培养方法及其分泌功能,为甲状旁腺细胞移植奠定实验基础。方法:胶原酶和胰蛋白酶系列消化甲状旁腺后,进行细胞培养。透射电镜检查培养5d的甲状旁腺细胞,对1、3、5、7d的细胞培养液行甲状旁腺激素测定。结果:培养5d的甲状旁腺细胞具有丰富的粗面内质网、高尔基复合体、杆状的线粒体和分泌颗粒。甲状旁腺细胞经过培养后可以正常分泌甲状旁腺激素,以第5天为最佳。结论:培养5d的甲状旁腺细胞仍保持原有的形态结构,分泌功能最强,可作为同种移植的最佳供体。
Objective：To investigate the culture technique and secretory function of parathyroid cells in rats in order to establish experimental basis of parathyroid cell transplantation.Methods：After parathyroid glands were digested by collagenase and trypsin,isolated parathyroid cells were cultured.The cells cultured for 5 days were observed by transmission electron microscopy.Parathyroid hormone obtained from the cell culture fluid on day 1,3,5 and 7 was measured respectively.Results：Parathyroid cells cultured for 5 days had abundant rough surfaced endoplasmic reticula、Golgi bodies、stab mitochondria and secretory granules.Cultured parathyroid cells could secrete parathyroid hormone normally,especially on the 5th day.Conclusion：Parathyroid cells cultured for 5 days still possess original morphologic structure and have maximum secreting function,so it is an optimal donor for transplantation.
