摘要(Abstract):
[目的]建立成人退变髓核细胞的单层培养模型并观察其形态;测定其细胞周期,探讨传代后髓核细胞生长不佳的原因。[方法]取24例椎间盘突出症患者手术切除的椎间盘组织,分离出髓核组织,胰酶和胶原酶消化,DMEM/12培养基培养。倒置相差显微镜观察其形态学特征,流式细胞分析仪检测原代和P2细胞周期。[结果](1)原代髓核细胞生长良好,7 d后贴壁生长的细胞可达90%。(2)原代细胞凋亡率为(38.10±11.7)%,P2代凋亡率为(44.74±17.6)%,原代S期细胞(7.88±2.1)%,P2 S期细胞(2.76±0.7)%。[结论]传代后的髓核细胞凋亡率增高,S期细胞减少明显。
