Figure 5.
The effect of Mcam silencing on migration of B16F10 cells. (a-c) The images of a wound healing assay were taken 48 hours after magnetofection (MF) and gene electrotransfer (EP) with pMCAM under visible light, 4× magnification and at 0, 8, and 15 hours, as designated, after the removal of a silicone cell-separator. Scale bar, 500 µm. (d) The kinetic analysis of cell migration. Bars represent AM ± SEM of the cell migration rate (N = 5). Asterisks indicate statistically significant differences between five control groups (untreated cells, only pSCR or pMCAM separately added to cells, MF or EP, MF + pSCR or EP + pSCR) and the group compared (MF + pMCAM or EP + pMCAM) (*P < 0.05). Crosses indicate statistically significant differences between MF + pMCAM and EP + pMCAM (†P < 0.05). All data are normalized to the untreated cells.
