发布时间:2022-12-11 04:47
[目的]探寻Wnt/β-catenin信号通路对诱导hUC-MSCs肝样细胞分化的影响及其机制。[方法]1.hUC-MSCs原代分离培养与鉴定:采用组织块贴壁法分离培养hUC-MSCs,经贴壁筛选纯化后,培养并传代,取第4代贴壁生长的细胞制备成单细胞悬液,运用流式细胞仪对细胞分子标志进行检测鉴定,并将hUC-MSCs诱导分化为成脂、成骨细胞,对其多向分化能力进行鉴定,以鉴定获得细胞性质和质量。2.检测Wnt/β-catenin信号通路激活剂与抑制剂对hUC-MSCs肝样分化的影响:将培养至第4-6代hUC-MSCs分成四组,分别为对照组(10%FBS的DMEM培养液培养),常规诱导肝向分化组,激活剂Wnt3a组(在常规诱导肝向分化基础上加入20ng/ml激活剂Wnt3a),抑制剂Dkk-1组(在常规诱导肝向分化基础上加入20ng/ml抑制剂Dkk-1)。各组分别在第7、14、21、28天收集细胞,采用荧光定量PCR检测与肝细胞分化相关基因如AFP、ALB、HNF4α、CK-19、TAT 和 Wnt/β-catenin 信号通路关键分子 Wnt1、β-catenin、GSK-3β mRN...
