摘要:

本研究旨在建立雷州山羊脐带间充质干细胞(LZG-UCMSCs)的分离培养体系,并探讨其治疗小鼠药物性肝损伤(DILI)的效果。选用9日龄的雷州山羊进行脐带间充质干细胞(UCMSCs)的分离培养,并开展生长曲线检测、细胞克隆、RT-PCR、免疫荧光和诱导试验,检验分离的细胞是否为UCMSCs。将36只ICR小鼠随机分为3组:空白对照组、模型损伤组、干细胞治疗组,每组12只。模型组和治疗组按照15 mg·kg-1的剂量对小鼠进行异烟肼灌胃,持续4周,然后检测血清中谷丙转氨酶(ALT)、谷草转氨酶(AST)和碱性磷酸酶(ALP)水平。结果表明,分离培养的LZG-UCMSCs的细胞形态正常,具有UCMSCs的特性,与对照组相比,损伤组ALT、AST和ALP水平显著升高(P < 0.05);与损伤组相比,治疗组ALT、AST和ALP水平极显著降低(P < 0.01)。结果提示,可以从雷州山羊脐带中分离出正常的UCMSCs,LZG-UCMSCs对小鼠DILI有一定的治疗作用,研究结果对LZG-UCMSCs进一步治疗山羊同源DILI具有一定参考价值。

Abstract:

The aim of this study was to observe the isolation and culture of Leizhou goat umbilical cord mesenchymal stem cells (LZG-UCMSCs) and the effect on the treatment of drug-induced liver injury (DILI) in mice. Umbilical cord mesenchymal stem cells were isolated and cultured, growth curve, cell cloning, RT-PCR, immunofluorescence and induction experiments were performed from nine-year-old Leizhou goat placenta. 36 ICR mice were randomly divided into 3 groups: blank control group, model injury group and stem cell treatment group, with 12 mice in each group. The rats in the model group and the treatment group were given gavage at a dose of 15 mg·kg-1 for 4 weeks. Aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were measured. The results showed that the cell morphology of the isolated and cultured LZG-UCMSCs was normal, with the characteristics of UCMSCs. Compared with the control group, the activities of ALT, AST and ALP in the injured group were significantly increased (P < 0.05). Compared with injury group, ALT, AST and ALP in treatment group were significantly decreased (P < 0.01). The results suggest that normal UCMSCs can be isolated from the placenta of Lezhou goat, and LZG-UCMSCs has a certain therapeutic effect on DILI in mice, thus providing reference value for further treatment of homologous goat DILI by LZG-UCMSCs.
