Liao Jin-mao, Hu Xiao-xuan, Li Zhuo-ri . Human umbilical cord blood mesenchymal stem cell transplantation improves the liver function of liver cirrhosis rats[J]. Chinese Journal of Tissue Engineering Research, doi: 10.3969/j.issn.2095-4344.2013.27.010.
人脐血间充质干细胞移植后4周,细胞移植组大鼠仍有部分肝细胞水肿、脂肪变性、细胞坏死,汇管区炎性细胞浸润等改变;肝内纤维组织增生,可见部分不完全纤维间隔形成;但与模型组比较,细胞移植组大鼠肝细胞脂肪变性、细胞坏死等程度均减轻(P < 0.05);肝纤维化程度明显改善(P < 0.01)。 2.7 Brdu标记的人脐血间充质干细胞的肝内定植情况 免疫组化染色显示,细胞移植组大鼠肝脏中可见BrdU标记的人脐血间充质干细胞的分布,细胞核呈棕黄色,数量多少不等,呈颗粒样或弥漫性分布,且多定植于肝小叶周围门管区附近;模型组大鼠肝组织未见BrdU阳性细胞;对照组大鼠肝内可见少量BrdU标记的人脐血间充质干细胞的分布。经细胞计数,平均每100倍视野下细胞移植组大鼠肝内人脐血间充质干细胞的定植数量明显多于对照组(38.7± 9.8,12.7±4.8;P < 0.01),见图6。"
