摘要

目的:探讨间充质干细胞(MSCs)在缓解四氯化碳(CCl4)诱导大鼠肝损伤中的治疗潜力。方法:研究时间为2024年10月至2025年2月。80只大鼠(MSC分离组20只,另加60只)分为各组。阴性对照组给予橄榄油治疗,每周2次,连续9周;阳性对照组给予橄榄油中CCl4治疗,每周2次,连续9周;MSC试验组给予与阳性对照组相同的治疗,后给予MSC治疗,每周1次,连续4周。评估肝酶水平(ALT、ASP和ALP)和氧化-抗氧化参数(谷胱甘肽过氧化物酶、超氧化物歧化酶、丙二醛、谷胱甘肽过氧化物酶、过氧化氢酶活性和总抗氧化能力)。对肝组织进行组织病理学分析,检查肝损伤程度。结果:与阴性对照组相比,阳性对照组肝酶和氧化应激标志物升高。MSC实验组表现出肝酶水平降低,抗氧化活性增强,组织学结果改善,炎症和纤维化减少。结论:间充质干细胞通过恢复抗氧化防御、减少氧化应激和促进组织再生,具有有效的肝保护作用。临床意义:该研究支持基于msc的治疗方法作为一种有希望的方法治疗由毒性损伤(如CCl4)引起的肝损伤的潜力。

Hepatoprotective effects of mesenchymal stem cells in carbon tetrachloride-induced liver toxicity in rats: restoration of liver parameters and histopathological evaluation.

Objective: To evaluate the therapeutic potential of mesenchymal stem cells (MSCs) in alleviating carbon tetrachloride (CCl4)-induced liver damage in rats.

Methods: The study was conducted from October 2024 through February 2025. A total of 80 rats (20 rats for MSC isolation and 60 additional rats) were divided into groups. The negative control groups received olive oil twice weekly for 9 weeks, a positive control group received CCl4 in olive oil twice weekly for 9 weeks, and an MSC test group received the same treatment as the positive control group, followed by treatment with MSCs once a week for 4 weeks. Liver enzyme levels (ALT, ASP, and ALP) and the oxidant-antioxidant parameters (glutathione peroxidase, superoxide dismutase, malondialdehyde, glutathione peroxidase, catalase activity, and total antioxidant capacity) were assessed. Histopathological analysis of liver tissues was performed to examine the extent of liver damage.

Results: The results showed increases in liver enzymes and oxidative stress markers in the positive control group compared to the negative control group. The MSC test group exhibited reduced liver enzyme levels, enhanced antioxidant activity, and improved histological findings, with reduced inflammation and fibrosis.

Conclusions: MSCs possess a potent hepatoprotective effect through the restoration of antioxidant defenses, reduction of oxidative stress, and promotion of tissue regeneration.

Clinical relevance: This study supports the potential of MSC-based therapy as a promising approach for the treatment of liver damage caused by toxic insults, such as CCl4.

期刊介绍: The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
