摘 要:探討北京鴨腎臟間充質(zhì)干細(xì)胞對(duì)脂多糖(Lipopolysaccharide , LPS)誘導(dǎo)小鼠急性損傷的免疫反應(yīng).用LPS對(duì)小鼠進(jìn)行腹腔注射,制作急性組織損傷模型,用北京鴨腎臟間充質(zhì)干細(xì)胞對(duì)小鼠進(jìn)行腹腔注射.實(shí)驗(yàn)結(jié)果表明,LPS誘發(fā)炎癥反應(yīng)后,取對(duì)數(shù)生長(zhǎng)期能分泌一定抗炎物質(zhì)且生長(zhǎng)增殖活力旺盛的間充質(zhì)干細(xì)胞注入小鼠體內(nèi),可顯著降低TNFɑ和CRP水平,調(diào)節(jié)促炎因子IL4和IL10對(duì)炎癥的應(yīng)答反應(yīng),說(shuō)明間充質(zhì)干細(xì)胞對(duì)急性炎性反應(yīng)有一定的作用.
