Fig. 6

Histological optical microscope cross-sections of the implanted biomaterial in Wistar Rats tibial defect. Optical microscopy images by groups (rows) and the magnifications (columns). The red arrows indicate the presence of unabsorbed graphene debris, osteoblasts, osteocytes and capillaries within the immature newly formed bone. The green arrows indicate more mature bone with vascularization and osteocytes in more restricted gaps without the presence of graphene. Both are indicated in 10 and 40x magnification of CAG Group cross sections.
