摘要:

背景:研究表明,脐血间充质干细胞可在特定环境下诱导为肝样细胞,移植入体内能行使正常肝细胞的功能。
目的:应用四氯化碳诱导制作大鼠肝硬化模型,观察脐血间充质干细胞移植对肝硬化模型大鼠的治疗作用。
方法:经四氯化碳诱导制作大鼠肝硬化模型,将20只肝硬化SD大鼠随机分为2组,对照组经尾静脉注射0.5 mL生理盐水,治疗组经尾静脉注射氯甲基苯甲酰胺标记的脐血间充质干细胞混悬液,干细胞量为1×106个。2周后处死所有大鼠,取大鼠静脉血检测肝功能指标,并行肝脏组织切片观察。
结果与结论:肝硬化模型大鼠肝细胞疏松、浊肿,部分细胞变性、坏死,肝小叶结构模糊不清,有多个大小不等的假小叶形成,符合肝硬化诊断标准。与对照组相比,治疗组大鼠血清白蛋白质量浓度显著增高(P < 0.05),胆红素浓度显著降低(P < 0.05),转氨酶活性显著降低(P < 0.05)。治疗组大鼠肝脏内有大量氯甲基苯甲酰胺标记的红色脐血间充质干细胞。提示脐血间充质干细胞可通过肝硬化模型大鼠尾静脉有效改善肝组织的生理功能。

Abstract:

BACKGROUND: Studies have shown that cord blood mesenchymal stem cells can be induced into hepatocyte-like cells in a specific environment, and the transplanted cells can exercise the normal function of liver cells.
OBJECTIVE: To establish the rat model of hepatic cirrhosis induced with carbon tetrachloride, and to observe the therapeutic effect of umbilical cord blood mesenchymal stem cell transplantation on a rat model of hepatic cirrhosis.  
METHODS: Hepatic cirrhosis models were established through carbon tetrachloride inducing, then 20 rat models of hepatic cirrhosis were randomly divided into two groups. The control group was injected with 0.5 mL normal saline via the tail vein; the treatment group was injected with chloromethyl benzamide labeled umbilical cord blood mesenchymal stem cell suspension, and the number of the stem cells was 1×106. After 2 weeks, all animals were sacrificed. Liver tissues were obtained for the histological observation and the venous blood was collected to detected the liver function indicators.
RESULTS AND CONCLUSION: The liver cells of the hepatic cirrhosis models were loose and cloudy swelling, part of the cells were degenerated and necrosis, the structure of the hepatic lobule was vague, and several pseudolobules with different sizes were formed which meet the diagnostic criteria of hepatic cirrhosis. Compared with the control group, the level of serum albumin in the treatment group was significantly increased (P < 0.05), while the levels of bilirubin and transaminases in the treatment group were significantly decreased (P < 0.05). There were lots of red chloromethyl benzamide labeled umbilical cord blood mesenchymal stem cells in the liver tissue of the treatment group. Human umbilical cord blood mesenchymal stem cells can effectively improve the physiological function of hepatic cirrhosis through tail vein.
