摘要:
目的研究改良体外小胶质细胞分离培养的方法及效果。传统法存在动物用量大、成本高且细胞培养时间长等局限。方法结合消化试剂组合和手摇震荡法培养分离小胶质细胞;同时采用Iba1免疫荧光法进行细胞鉴定和纯度分析,台盼蓝染料法进行活力检测以及脂多糖刺激比较不同状态的小胶质细胞。 结果改良法可在4 d内稳定获得小胶质细胞>1.0×106个/60 mm培养皿,纯度≥98%,活力>98%,较传统法在动物用量、总成本和培养时间分别减少了2、3.2、1.5倍。结论改良法可减少动物用量、降低成本,缩短细胞培养时间;为研究小胶质细胞的生物学功能和中枢神经系统疾病机制建立了一种稳定、简便、高效的细胞模型。
Abstract:
Abstract: ObjectiveIsolation and culture of microglia in vitro has been widely used to explore new therapeutic strategies for various central nervous system diseases, but the existing protocols need a large amount of animal, higher cost and long culture time. MethodsCombination of a unique combination of digestive reagents and shaking by hand were used to isolate and purify microglia. The purity of isolated cells was identified by expression of Iba1 utilizing immunofluorescence technique and the viability of microglia was determined with trypan blue exclusion. Meantime, comparing the different states of microglia using the lipopolysaccharide test. ResultsThe present modified methodology steadily yielded 1.0×106 microglia per 60 mm dish with high purity(≥98%) and high survival rate(>98%) within four days. Compared to the existing protocols, the animal dosage, total cost and culture time were reduced by 2, 3.2 and 1.5 times, respectively. ConclusionThe improved method establishes a stable, simple and efficient cell culture model for studying the biological functions of microglia and elucidating the mechanisms of related CNS diseases.
