摘要:

文题释义

弥漫性大B细胞淋巴瘤细胞条件培养液:人弥漫性大B细胞淋巴瘤细胞在生长过程中向培养液中释放多种活性物质,包括生长因子和细胞因子。收集弥漫性大B细胞淋巴瘤细胞培养基上清液,使用截留分子质量为100 kD的超滤离心管,3 000 r/min离心30 min,经过滤除菌后即得到弥漫性大B细胞淋巴瘤细胞条件培养液。
人骨髓间充质干细胞:是一种具有异质性的细胞群,能够自我更新并分化为成骨细胞、脂肪细胞及软骨细胞等多种细胞类型。骨髓间充质干细胞可以根据其所暴露的肿瘤微环境来获得促肿瘤和抗肿瘤表型,从而促进或抑制肿瘤生长。

摘要
背景:骨髓微环境与弥漫性大B细胞淋巴瘤生长、存活和耐药性之间的关系是近些年的研究热点,而弥漫性大B细胞淋巴瘤细胞条件培养液对骨髓间充质干细胞的影响未见报道。
目的:探讨弥漫性大B细胞淋巴瘤细胞条件培养液对骨髓间充质干细胞增殖和凋亡的影响。 
方法:采用Ficoll密度梯度离心法从健康供者骨髓血中分离骨髓间充质干细胞,并通过贴壁法进行纯化;使用SU-DHL-2和OCI-LY3两种弥漫性大B细胞淋巴瘤细胞培养上清液制备条件培养液。按培养基的不同进行细胞分组:对照组骨髓间充质干细胞仅用L-DMEM完全培养液培养,CM-SU-DHL-2组、CM-OCI-LY3组骨髓间充质干细胞用20% SU-DHL-2细胞条件培养液或20% OCI-LY3细胞条件培养液和80% L-DMEM完全培养液培养。通过CCK-8、EDU、结晶紫染色观察骨髓间充质干细胞的增殖情况,划痕实验评估骨髓间充质干细胞的迁移情况,流式细胞术检测骨髓间充质干细胞的细胞周期、凋亡情况,Real-time PCR和Western blot检测骨髓间充质干细胞中P21、P16、Bcl-2、BTK mRNA和蛋白表达水平。 

结果与结论:①与对照组相比,SU-DHL-2和OCI-LY3细胞条件培养液显著促进骨髓间充质干细胞的增殖(P < 0.05),可能与P21和P16蛋白低表达密切相关(P < 0.05);②与对照组相比,SU-DHL-2和OCI-LY3细胞条件培养液显著促进骨髓间充质干细胞的迁移(P < 0.05);③与对照组相比,SU-DHL-2和OCI-LY3细胞条件培养液抑制骨髓间充质干细胞的凋亡(P < 0.05),可能与Bcl-2、BTK mRNA和蛋白高表达密切相关(P < 0.05)。研究结果表明,弥漫性大B细胞淋巴瘤细胞条件培养液可促进骨髓间充质干细胞的增殖并抑制凋亡。

Abstract: BACKGROUND: The relationship between bone marrow microenvironment with growth, survival, and drug resistance of diffuse large B-cell lymphoma has become a hot topic of research, but the effect of diffuse large B-cell lymphoma cell conditioned medium on bone marrow mesenchymal stem cells has not been reported.
OBJECTIVE: To investigate the effect of cell conditioned medium of diffuse large B-cell lymphoma on proliferation and apoptosis of bone marrow mesenchymal stem cells.
METHODS: Bone marrow mesenchymal stem cells were extracted from bone marrow blood of healthy donors by Ficoll density gradient centrifugation method and purified by adhesion method. Meanwhile, two kinds of diffuse large B-cell lymphoma cell supernatant (SU-DHL-2 and OCI-LY3) were used to prepare conditional culture medium. The cells were grouped according to different media: human bone marrow mesenchymal stem cells in the control group were cultured with L-DMEM only. The human bone marrow mesenchymal stem cells in the CM-SU-DHL-2 and CM-OCI-LY3 groups were cultured with 20% SU-DHL-2 cell conditioned culture medium or 20% OCI-LY3 cell conditioned culture medium and 80% L-DMEM complete culture medium. The proliferation of bone marrow mesenchymal stem cells was observed by CCK-8, EDU and crystal violet staining. The migration of bone marrow mesenchymal stem cells was evaluated by scratch method. The cell cycle and apoptosis of bone marrow mesenchymal stem cells were detected by flow cytometry. The expression levels of P21, P16, Bcl-2, and BTK mRNA and protein were detected by real-time PCR and western blot assay. 
RESULTS AND CONCLUSION: (1) Compared with the control group, the conditioned medium of SU-DHL-2 and OCI-LY3 cells could significantly promote the proliferation of bone marrow mesenchymal stem cells (P < 0.05), which might be closely related to the low expression of P21 and P16 proteins (P < 0.05). (2) Compared with the control group, the conditioned medium of SU-DHL-2 and OCI-LY3 cells significantly promoted the migration of bone marrow mesenchymal stem cells (P < 0.05). (3) Compared with the control group, the conditioned medium of SU-DHL-2 and OCI-LY3 cells inhibited the apoptosis of bone marrow mesenchymal stem cells (P < 0.05), which might be closely related to the high expression of Bcl-2 and BTK mRNA and protein (P < 0.05). The results showed that the conditioned medium of diffuse large B-cell lymphoma cells could promote the proliferation and inhibit apoptosis of bone marrow mesenchymal stem cells.
