Table 1.

Images used in this study. Cells were stained with 0.1% crystal violet for 20 minutes for the deep staining group and 8 minutes for the light staining group. High density images refer to those having over 400 cells and low density images refer to those having less than 200 cells. Biology stimulation of cells was discussed in Section 2.
