Values (µm) represent the means ± standard deviation (SD) calculated from 50 cells. A two-way ANOVA was performed to compare the significance of differences between the means. Mean values with common superscript letters are not significantly different from each other (p ≤ 0.05) by Tukey’s HSD test.
