Time-dependent changes in average thickness of GAG-stained area in CF layer. The average thickness of the GAG-stained area in the resection group at 6 weeks was lower than that in the sham group. Shaded bars: Resection group, Unshaded bars: Sham group Safranin-O staining of histological sections of at 6 weeks in CF layer; (b): resection group, (d): sham group. (c) and (e) are magnified views of the boxed part in (b) and (d). The GAG staining density in the resection group was lower than that in the sham group.
