Figure 7.

The wound healing assay can reveal differences in migration rates. As an illustration, the sheet migration rates of two different epithelial cell lines (BEAS and MCF7) were determined by plotting the gap area versus time. Two representative data sets for each cell line are plotted in (A). The slope of the resultant graphs yield migration rates in μm/hr. In (B), the average migration rate for both cell types is shown (6 replicates were carried out for each cell line). It can be seen that the sheet migration rate of BEAS cells is more than twice that of the MCF7 cells.
