Figure 14. Comparison of invasion property between epithelial cell adhesion molecule (EpCAM)⁺ and EpCAM^- cells. A: Representative microscopy picture showing the invasion of EpCAM^– Y79 cells. B: Representative microscopy picture showing the invasion of EpCAM⁺ Y79 cells. C: Bar diagram showing increased number of EpCAM⁺ cells (bar 2) invading the matrigel compared to EpCAM^– cells (bar 1). Smilarly, bar 4 shows decrease in the invasion of EpCAM⁺ cells treated with EpCAM specific small interfering RNA when compared to small interfering RNA (siRNA) untreated EpCAM⁺ cells (bar 3). The error bars represent standard error mean of triplicate values. For statistical analysis, group 2 was compared with group 1 and group 4 was compared to group 3. Asterisk mark represent p value less than 0.05 which is statistically significant as analyzed by t-test.
