Myopic cells elevate traction force that is restored to the level of healthy corneal cells after recovery to the healthy state. (a) Myopic cells generate higher levels of traction force than control cells. The traction force of both myopic and control corneal cells was measured by traction force microscopy on 8-kPa polyacrylamide gels. n = 3 independent experiments. ^∗p < 0.05. (b) Representative images of traction forces in myopic and control cells. (c) Recovered cells generate similar traction force to control cells. n = 3 independent experiments. NS, no significance. (d) Representative images of traction forces in recovered and control cells. The number of cell samples was shown in the figures. To see this figure in color, go online.
