Figure 6. TβRII siRNA blocks SRA01/04 cells migration. Inverted microscope images demonstrating migration of HLECs (A), cells treated for 48 h with scrambled siRNA (B), or cells treated for 48 h with 80 nM hT3 (C). Black straight lines mark the wound edges. D: Bar graph showing mean cell numbers migrating to wound area in each specimen (n=10); error bars represent the standard error of the mean. Asterisks denote values significantly different from those of scrambled siRNA treated controls (p<0.0001). Experiments were repeated 3 times, yielding similar results. The bar represents 25 μm.
