Directional cell migration requires cell polarization. The reorganization of the Golgi apparatus is an important phenomenon in the polarization and migration of many types of cells. Direct current electric fields (dc (EF) induced directional cell migration in a wide variety of cells. Here nHDFs migrated toward cathode under 1 V/cm dc EF, however 1 μM of brefeldin A (BFA) inhibited the dc EF induced directional migration. BFA (1 μM) did not cause the complete Golgi dispersal for 2 h. When the Golgi polarization maintained their direction of polarity, the direction of cell migration also kept toward the same direction of the Golgi polarization even though the dc EF was reversed. In this study, the importance of the Golgi polarization in the directional migration of nHDf under dc EF was identified.
定向细胞迁移需要细胞极化。高尔基体的重新组织是多种细胞极化和迁移过程中的一个重要现象。直流电场(dc(EF))可诱导多种细胞发生定向迁移。在这里,正常人皮肤成纤维细胞(nHDFs)在1 V/cm的直流电场作用下向阴极迁移,然而1 μM的布雷菲德菌素A(BFA)抑制了直流电场诱导的定向迁移。1 μM的BFA在2小时内并未导致高尔基体完全分散。当高尔基体极化保持其极性方向时,即使直流电场反转,细胞迁移方向也会保持与高尔基体极化相同的方向。在本研究中,确定了高尔基体极化在直流电场作用下nHDf定向迁移中的重要性。
