文题释义:
脂肪间充质干细胞移植:
人或者动物的脂肪组织经培养后可能得到具有复制和分化潜能的脂肪源性间充质干细胞,脂肪间充质干细胞具有和骨髓间充质干细胞相似的特性,具有相似的标记抗原、基因转导能力、多向分化能力等。与骨髓间充质干细胞相比,具有取材方便、细胞获得率高、增殖不需要特定血清或基质补充等优点,因此具有比骨髓间充质干细胞更为广泛的应用前景。
肝纤维化:是多种原因引起的慢性肝损害所致的病理改变,表现肝为内细胞外间质成分过度异常地沉积,并影响肝脏的功能,是慢性肝病发展到肝硬化必经之阶段。肝纤维化形成过程已趋明朗,其形成过程与血清生化有关,大致可分为慢性肝损害,细胞因子网络失调和细胞外间质代谢异常3个环节。任何原因如肝炎病毒、血吸虫病、酒精、药物及毒物等长期持续损害肝脏,都将导致肝纤维化形成,所以肝纤维化的病因是多样的、复杂的。

 

摘要
背景:
干细胞移植是晚期肝病比较有前景的治疗方法,脂肪间充质干细胞是继骨髓间充质干细胞后的又一研究热点。
目的:观察脂肪间充质干细胞移植后对肝硬化大鼠血生化指标的影响作用。
方法:将60只大鼠随机分为正常对照组、模型组及脂肪间充质干细胞组,各20只。模型组及脂肪间充质干细胞组采用四氯化碳灌胃诱导建立肝硬化大鼠模型。建模成功后1周,脂肪间充质干细胞组腹腔注射脂肪间充质干细胞悬液,正常对照组及模型组注射生理盐水。
结果与结论:与对照组相比,模型组大鼠肝组织中丙氨酸氨基转移酶、门冬氨酸氨基转移酶、总胆红素、总蛋白含量及血清丙二醛含量显著升高,血清白蛋白、血清蛋白含量与球蛋白比值及肝组织中谷胱甘肽过氧化物酶及环磷酸鸟苷含量明显下降,且吲哚氰绿 15 min滞留率及肝纤维化程度明显上升,而与模型组相比,脂肪间充质干细胞组相比丙氨酸氨基转移酶、门冬氨酸氨基转移酶、总胆红素、总蛋白含量及血清丙二醛含量显著下降,血清白蛋白、血清蛋白含量与球蛋白比值肝组织中明显升高,且吲哚氰绿 15 min滞留率及肝纤维化程度明显减轻,同时脂肪间充质干细胞组大鼠肝脏组织中可见CM-Dil标记的阳性脂肪间充质干细胞。提示脂肪间充质干细胞能够影响大鼠肝硬化的血生化指标水平,脂肪间充质干细胞移植后可以减轻大鼠肝硬化程度。

Abstract:

BACKGROUND: Stem cell transplantation is a promising treatment of advanced liver disease, and adipose-derived mesenchymal stem cells have become another kind of popular cells following bone marrow mesenchymal stem cells.
OBJECTIVE: To investigate the influence of adipose-derived mesenchymal stem cell transplantation on blood biochemical indices of liver cirrhosis rats.
METHODS: Sixty rats were equally randomized into normal control, model and cell transplantation groups. Model rats of liver cirrhosis were made in the latter two groups through intragastric administration of carbon tetrachloride. One week after successful modeling, rats were given intraperitoneal injection of adipose-derived mesenchymal stem cell suspension in the cell transplantation group, and given normal saline in the other two groups.
RESULTS AND CONCLUSION: Compared with the normal control group, the model group showed a significant increase in the levels of alanine aminotransferase, aspartate aminotransferase, total bilirubin, total protein in liver tissues, serum level of malondialdehyde, 15-minute indocyanine green retention rate and degree of hepatic fibrosis, and a significant decrease in serum albumin level, serum albumin/globulin, levels of glutathione peroxidase and cyclic guanosine monophosphate in liver tissues. On the contrary, these indicators were all improved in the cell transplantation group compared with the model group. Moreover, CM-Dil-positive cells were visible in the liver tissue of rats undergoing adipose-derived mesenchymal stem cell transplantation. All these findings indicate that adipose-derived mesenchymal stem cell transplantation can reduce liver cirrhosis in rats by acting on blood biochemistry levels.
