Abstract:

BACKGROUND: Studies have shown that umbilical cord mesenchymal stem cells (UC-MSCs) can be induced to differentiate into liver cells, playing a role in liver repair.
OBJECTIVE: To explore the effect of taurine combined with UC-MSCs transplantation on liver injury repair.
METHODS: Forty healthy Sprague-Dawley rats were used to make chronic alcoholic liver injury models through intragastric administration of 56 degrees liquor, and then randomized into model group, UC-MSCs group and combined treatment group (taurine combined with UC-MSCs transplantation). Model rats were given portal vein injection of 1 mL normal saline in the model group, 1 mL UC-MSCs suspension in the UC-MSCs group, and 0.28 g/L taurine plus 1 mL UC-MSCs in the combined treatment group. Two weeks after transplantation, levels of serum superoxide dismutase, glutathione peroxidase, catalase, alanine aminotransferase, malondialdehyde, endotoxin and interleukin-4 were detected. RT-PCR was used to detect CYP2B1 mRNA expression.
RESULTS AND CONCLUSION: Levels of serum superoxide dismutase, glutathione peroxidase, catalase and alanine aminotransferase were highest in the combined treatment group, higher in the UC-MSCs group and lowest in the model group (P < 0.05). The levels of malondialdehyde, endotoxin and interleukin-4 were ranked as follows: combined treatment group < UC-MSCs group < model group (P < 0.05). RT-PCR findings showed that the CYP2B1 mRNA expression was increased significantly in the combined treatment group as compared with the UC-MSCs and model groups (P < 0.05). Taken together, our experimental findings suggest that UC-MSCs transplantation, especially in combination with taurine, can promote recovery from liver injury in rats, which is probably related to a reduction in free radicals that trigger a damage to the body.
