Fig. 4: µCT and histological analysis of the distal condyle defect model at 2 and 4 weeks postsurgery (scale bar: 2 mm).
From: Tough and biodegradable polyurethane-silica hybrids with a rapid sol-gel transition for bone repair

A Representative top- and side-view images of the defect site. The red dotted lines in the top-view images represent the sliced region in the side-view images. The yellow dotted lines in the side-view images represent the defect sites. Bone volume fraction (BV/TV, %) of the newly formed bones at 2 and 4 weeks postsurgery (n = 3) (*p < 0.05). B Hematoxylin and eosin (H&E) staining of the distal condyle bone defects with enlarged images within the defect sites (scale bar: 500 μm) and morphology of the defects stained with Masson’s trichrome (MT) staining (scale bar: 500 μm).
