From: Clinical trial and in-vitro study comparing the efficacy of treating bony lesions with allografts versus synthetic or highly-processed xenogeneic bone grafts

a/b: Histologic overview of allogeneic human cancellous bone (cryopreserved, caput femoris, DIZG) prior to use (a). Osteocytes and adipocytes are visible (arrows). Newly-formed bone is stained dark magenta, older bone light magenta. Soft tissue (blue) with fibrocytes (arrow) is visible adjacent to the bone trabeculae. Undecalcified ground sections, stained with azure II and pararosaniline, original magnification x 100 and x 400. The highly-processed xenogeneic bone graft (Orthoss®/BioOss®) prior to use does not exhibit any cells or cell remnants (b). In contrast to allogeneic cancellous bone, no soft tissue (blue) is detectable. Empty osteocyte lacunae are visible (arrows). Undecalcified ground sections, stained with azure II and pararosaniline, original magnification x 50, x 100 and x 200
