Figure 4. Migration of RPE cells in response to TCS-401 treatment. A: Migration assay confirmed that TCS-401 increased the number of migrated RPE cells. Original magnification=100X. B: The number of migrated cells per HPF is shown. The data represent the mean±standard deviation of three independent experiments. *p<0.05, compared to the control group. HPF, high-power field; RPE, retinal pigment epithelium.
