The adhesion ability, the migrated ability and invasive ability were determined with the laminin adhesion test, the chemotactic migration test and the invasion test of reconstituted basement membrane.

用层粘连蛋白粘附测定法、纤粘蛋白趋化迁移测定法和重建基底膜侵袭测定法测定肺癌细胞的粘附、运动和侵袭能力。

Results: Researchs indicated that various tumor cells expressed chemotactic factor CXCL12 and its receptor CXCR4, which was closely related to migration and metastasis of tumor cells.

结果：研究表明许多肿瘤细胞表达趋化因子CXCL12和受体CXCR4，与肿瘤细胞的迁移与转移有密切关系。
