Fig. 3: Histologic differences between experimental and control groups 4 weeks post-operatively.

A Control group showing numerous blood vessels containing red corpuscles of red blood cells are found in the marrow spaces surrounding the newly formed bone trabeculae. (H&E; original magnification ×100). B Test group shows a huge amount of blood vessels with marrow spaces surrounding the trabeculae of the newly formed bone (H&E; original magnification ×100). C Control group light micrograph showing mature bone within defect with wide marrow spaces of moderate vascularity (Masson’s trichrome; original magnification ×100). D Test group light micrograph showing newly formed bone lined by active osteoblast. Fibrous mapping of newly formed trabeculae is also noticed. (Masson’s trichrome; original magnification ×100).
