FIGURE 7.

Cell viability and morphology of human keratinocyte cells (HaCaT cells) treated with PS1-70 or PS1-120. (A) Cell viability of HaCaT, incubated at 37°C for 24 h in the absence (NT) or presence of PS1-70 or PS1-120 at 100 nM, was evaluated by CCK-8 assay. (B) Phase-contrast microscopy images of HaCaT cells not treated (NT) or treated with 100 nM of PS1-70 or PS1-120 at 37°C for 24 h. The microscope images were representative of three independent experiments performed in triplicate. Bars are presented as mean (Student’s t-test, P < 0.05). Error bars indicate standard deviation.
