中文摘要：

目的观察人源脐带间充质干细胞（HUCMSC）对胶质瘤细胞株U87转移、侵袭能力的影响。方法建立细胞共培养体系，CCK8法、transwell法和Matrigel法分别检测HUCMSC与U87非接触共培养后，U87增殖、转移、侵袭能力变化。结果体外细胞共培养体系中，HUCMSC共培养U87组（实验组）比U87单独培养组（对照组）转移和侵袭能力都有显著提高（P〈0．05），HUCMSC共培养对U87有促增殖作用。结论在体外共培养体系中，HUCMSC可能通过促进EMT转化而提高胶质瘤细胞株U87增殖、转移和侵袭潜能。因此，在HUCMSC的临床转化应用中，应该考虑其可能的促肿瘤作用。

英文摘要：

Objective To observe the impacts of human umbilical cord mesenchymal stem cells （HUC-MSCs） on the metastasis and invasion of gtioma cell （GC） line U87. Methods A cell co-culture system was established. The changes in the proliferation, metastasis and invasion of U87 after the non-contact co-culture with HUC-MSCs were detected by CCK8 method, transwell method and Matrigel method, Results The metastasis and invasion of U87 co-cultured with HUC-MSCs （in the experiment group） were much better than those of U87 separately cultured （the control group）. Conclusion In the co-culture system in vitro, HUC-MSCs may improve the proliferation, metastasis and invasion of glioma cell line U87 by promoting EMT transformation. Therefore, the potential tumor promoting effects of HUC-MSCs should be considered in the clinical transformation application.
