摘要 目的探讨慢性粒细胞白血病(CML)患者骨髓间充质干细胞(BMSC)体外转化生长因子β受体2(TGF-βR2)和TGF-β1基因表达水平及其临床意义。方法无菌采集、分离5例CML患者和5例健康人对照组的骨髓单个核细胞,体外培养BMSC,观察BMSC形态及生长状态;实时荧光定量PCR分析TGF-βR2及TGF-β1 mRNA的表达水平。结果两组研究对象的BMSC形态类似;CML患者TGF-βR2、TGF-β1 mRNA表达水平分别为34.63±18.96和9.09±6.81,与健康人对照组的8.05±4.46和30.69±19.25比较,差异有统计学意义(t分别为2.37和3.05,P均<0.05)。结论 CML患者BMSC的TGF-βR2表达升高及TGF-β1表达降低与CML发生有关。
