發(fā)布時(shí)間:2022-12-11 04:47
[目的]探尋Wnt/β-catenin信號通路對誘導(dǎo)hUC-MSCs肝樣細(xì)胞分化的影響及其機(jī)制。[方法]1.hUC-MSCs原代分離培養(yǎng)與鑒定:采用組織塊貼壁法分離培養(yǎng)hUC-MSCs,經(jīng)貼壁篩選純化后,培養(yǎng)并傳代,取第4代貼壁生長的細(xì)胞制備成單細(xì)胞懸液,運(yùn)用流式細(xì)胞儀對細(xì)胞分子標(biāo)志進(jìn)行檢測鑒定,并將hUC-MSCs誘導(dǎo)分化為成脂、成骨細(xì)胞,對其多向分化能力進(jìn)行鑒定,以鑒定獲得細(xì)胞性質(zhì)和質(zhì)量。2.檢測Wnt/β-catenin信號通路激活劑與抑制劑對hUC-MSCs肝樣分化的影響:將培養(yǎng)至第4-6代hUC-MSCs分成四組,分別為對照組(10%FBS的DMEM培養(yǎng)液培養(yǎng)),常規(guī)誘導(dǎo)肝向分化組,激活劑Wnt3a組(在常規(guī)誘導(dǎo)肝向分化基礎(chǔ)上加入20ng/ml激活劑Wnt3a),抑制劑Dkk-1組(在常規(guī)誘導(dǎo)肝向分化基礎(chǔ)上加入20ng/ml抑制劑Dkk-1)。各組分別在第7、14、21、28天收集細(xì)胞,采用熒光定量PCR檢測與肝細(xì)胞分化相關(guān)基因如AFP、ALB、HNF4α、CK-19、TAT 和 Wnt/β-catenin 信號通路關(guān)鍵分子 Wnt1、β-catenin、GSK-3β mRN...
