扶正化瘀方对骨髓移植肝纤维化小鼠骨髓细胞肝脏迁移的影响
Chinese Journal of Experimental Traditional Medical Formulae(2010)
Abstract
目的:探讨扶正化瘀方(FZHY)对肝纤维化小鼠骨髓细胞肝脏归巢的作用。方法:BABL/C雌性受鼠性别交叉法骨髓移植模型基础上,四氯化碳(CCl4)诱导肝纤维化模型;成模后,治疗组以FZHY方4.6 g.kg-1.d-1 ig 4周。PCR,病理及肝功能检测成模情况;通过FISH法标记Y染色体,观察雌性受鼠肝脏内骨髓源性细胞含量;Western blot法检测雌性受鼠肝组织基质细胞衍生因子-1(SDF-1)蛋白相对表达量。结果:与模型组比较,FZHY组小鼠,肝组织损伤明显减轻。FISH法标记Y染色体观察显示,FZHY组小鼠较模型组肝内骨髓源性细胞减少(P<0.05)。Western blot结果,FZHY组小鼠较模型组肝脏SDF-1蛋白相对表达量明显减少(P<0.01)。结论:在肝脏损伤时,FZHY可能通过抑制肝内SDF-1蛋白的表达来阻止骨髓源性细胞迁移入肝,从而一定程度上抑制骨髓源性细胞入肝后促进肝纤维化。
