Morphological changes induced by cyclic mechanical stretch. a-f Phalloidin staining of RPE cells at different time points; g The spreading cell ratio at different time points (red fluorescence: phalloidin staining; and blue fluorescence: DAPI nuclear staining). The morphological change of RPE cells was dependent on the duration of the stretch. At 14 h of cyclic stretch, the spreading cell ratio started to decrease sharply (p < 0.01). At 6 h after withdrawal of the stretch (R6h), the spreading cell ratio was significantly higher than at 14 h and 20 h (p < 0.01)
