Rat calvaria healing 7 weeks after surgery in a guided bone regeneration model. Representative images of the defects with Movat’s pentachrome staining of undecalcified 7-µm thick frontal sections. The control represents the defects with the GBR membrane without bone grafts (unfilled defects). Scale bars: 250 µm for the histological full defects and 100 µm for the histological magnification (dashed square). Dark yellow: collagen in the bone tissue, light red: cytoplasms, dark red: osteoid borders, brown: nuclei, ft: fibrous tissue, oc: osteocytes, nb: newly formed bone, vs: blood vessels, gr: grafts.
