摘要 目的探讨体外5-溴脱氧尿嘧啶核苷(5-bromo-2-deoxyuridine,BrdU)标记兔骨髓间充质干细胞(bone marrow-derived mesenchymal stem cells,MSCs)的方法,探索BrdU体外标记兔MSCs的最佳时间和最佳浓度。方法通过形态学及流式细胞术鉴定全骨髓培养法分离培养的细胞为MSCs。MSCs经不同BrdU浓度标记及不同BrdU标记时间,免疫细胞化学法鉴定并评估。结果全骨髓培养法培养的MSCs经流式细胞术检测,证明所培养的细胞为较纯的MSCs。BrdU标记的阳性细胞率随标记时间延长以及标记物BrdU的浓度增加而逐渐增高,40μmol/L及72 h标记阳性率达85%~95%。结论应用BrdU体外标记MSCs是安全可靠的,兔MSCs体外BrdU标记最佳时间和最佳浓度分别为72 h和40μmol/L。
