文题释义:
骨髓瘤细胞:
具有无限分裂能力,由于该细胞并非高度分化细胞,因此分裂能力较强,而其它肿瘤细胞分裂能力较弱,因此多在制备单克隆抗体时与B淋巴细胞融合,使单克隆抗体迅速大量增殖。
多发性骨髓瘤患者骨髓微环境的异常:骨髓间充质干细胞作为骨髓微环境重要组成部分一员。骨髓瘤患者骨髓微环境中往往存在着白细胞介素1β、白细胞介素6等炎性因子水平的异常增高,这些异常水平的炎性因子不但直接作用于骨髓瘤细胞,而且还可以间接通过间充质干细胞等微环境中其他细胞,调节骨髓瘤细胞功能。但这些细胞因子短期或长期异常对骨髓瘤细胞的影响,目前尚不清楚。

 

摘要
背景:
既往多项研究提示多发性骨髓瘤患者间充质干细胞的细胞因子分泌、免疫调节、成骨分化等生物功能异常。
目的:观察白细胞介素1β单次或多次预处理的正常间充质干细胞后,其再与多发性骨髓瘤细胞株共培养,对骨髓瘤细胞干细胞相关基因、趋化相关受体等表达的影响。
方法:实验分为无白细胞介素1β预处理的骨髓间充质干细胞对照组、白细胞介素1β 预刺激 1 d及白细胞介素1β预刺激 7 d 组,各组分别培养7 d后,均加入骨髓瘤细胞株H929直接接触共培养。3 d后收集各组中骨髓瘤细胞株H929细胞,分别采用 Western blot方法检测各组细胞NANOG、SOX2 和OCT-4 蛋白的表达水平,RT-PCR 方法检测各组细胞趋化因子受体CCR1、CCR2、CCR6和CXCR4的基因表达水平。
结果与结论:①与对照组比较,H929细胞株和单次白细胞介素1β处理组及多次白细胞介素1β处理组共培养后,SOX2蛋白表达水平升高(P < 0.05);②与对照组、单次白细胞介素1β处理组比较,多次白细胞介素1β处理组CCR1和CCR2基因的表达水平均增高(P < 0.05);③实验结果显示,正常骨髓间充质干细胞经炎症因子白细胞介素1β单次或多次刺激后,在与骨髓瘤细胞的相互作用中,对骨髓瘤细胞的干细胞基因表达、细胞趋化因子受体表达等均产生影响。这提示骨髓微环境中异常水平炎性因子,除了直接作用于骨髓瘤细胞之外,很可能通过影响间充质干细胞等非骨髓瘤细胞后,间接参与骨髓瘤疾病的发生和发展,并且其对骨髓瘤细胞的影响效果与白细胞介素1β作用间充质干细胞的时间长短有关。

Abstract:

BACKGROUND: Many studies have showed that mesenchymal stem cells derived from multiple myeloma patients display a wide range of abnormal biological features, including cytokine secretion, immune regulation and osteogenic differentiation.
OBJECTIVE: To investigate the expression of stem cell-associated proteins and chemotaxis-related receptors genes in myeloma cells when co-cultured with pulsed or sustained interleukin-1β treated bone marrow mesenchymal stem cells.
METHODS: There were three groups in the experiment: untreated normal bone marrow mesenchymal stem cells as control, bone marrow mesenchymal stem cells only treated with interleukin-1β for 1 day as 1-day group or once a day for 7 days as 7-day group. After 7 days of culture, treated or untreated bone marrow mesenchymal stem cells were employed as coating feeder for the direct co-culture with H929 cells for 3 days. At the end of co-culture, H929 myeloma cells were harvested, the expression of NANOG, SOX2 and OCT-4 was measured by western blot, and mRNA levels of CCR1, CCR2, CCR6 and CXCR4 were detected by real-time PCR.
RESULTS AND CONCLUSION: The SOX2 protein levels in H929 cells were significantly higher in both 1-day and 7-day groups than that of control group (P < 0.05). In the respective of chemotaxis-related receptors, the mRNA levels of CCR1 and CCR2 in myeloma cells in 7-day group were significantly higher than those in both control and 1-day groups (P < 0.05). Our in vitro results impose inflammatory cytokine interleukin-1β in bone marrow microenvironment has direct effect on myeloma cells, but also regulates myeloma cells indirectly via non-myeloma cells such as mesenchymal stem cells; besides, sustained elevated interleukin-1β level in the bone marrow has more profound effects on myeloma cells through mesenchymal stem cells. Mesenchymal stem cells act an important cellular component involved in myeloma progression.
