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.
