H&E staining in the bipedal rat group (a–d) and normal group (e–h). Before the flexed brace wear (a, e), and 2 weeks (b, f), 4 weeks (c, g), and 6 weeks (d, h) after the flexed brace wear. The epiphyseal plate was composed of proliferating cartilage cell layers with an equal thickness, and chondrocytes were arranged in a regular fashion with clear tidal line in the whole area throughout the experiment. Scale bar = 100 μm
