目的  探討骨髓間充質(zhì)干細(xì)胞(BMSCs)移植修復(fù)大鼠肝缺血再灌注損傷的最佳劑量,為細(xì)胞移植修復(fù)肝缺血再灌注損傷提供前期的實(shí)驗(yàn)依據(jù)。
方法  采用全骨髓直接貼壁法分離培養(yǎng)BMSCs,取第4代細(xì)胞進(jìn)行移植。將30只健康雄性Wistar大鼠建立肝缺血再灌注損傷模型后,隨機(jī)分成空白對照組、5×105個組、1×106個組、2×106個組及3×106個組5組,每組6只。后4組大鼠均在建立肝缺血再灌注損傷模型后,立即抽取200 μL細(xì)胞懸液(數(shù)量分別為5×105、1×106、2×106及3×106個),通過門靜脈注射;空白對照組大鼠注射等體積的PBS溶液。于移植術(shù)后24 h采血檢測血清天門冬氨酸氨基轉(zhuǎn)移酶(AST)和丙氨酸氨基轉(zhuǎn)移酶(ALT)水平;取肝臟組織檢測丙二醛(MDA)含量、超氧化物歧化酶(SOD)活性及核因子-κB (NF-κB) p65蛋白的表達(dá),并行HE染色。
結(jié)果  1×106個組和2×106個組與空白對照組、5×105個組及3×106個組比較,其AST、ALT及MDA水平均降低(P<
0.05),而SOD活性均增高(P<0.05);NF-κB p65蛋白的表達(dá)均明顯下調(diào);肝組織的病理學(xué)損傷均改善。但該2組的AST、ALT、MDA及SOD水平比較差異均無統(tǒng)計學(xué)意義(P>0.05),且肝組織的病理學(xué)改變也無明顯差別。
結(jié)論  大鼠BMSCs移植治療肝缺血再灌注損傷的最佳劑量為1×106個細(xì)胞。
