Histological analysis of implant samples after 4 and 12 weeks in rabbit radius defect sites. Van Gieson's staining of the PT and GMPT scaffolds at 4 and 12 weeks after the operation was carried out to evaluate osteogenesis and angiogenesis. The GMPT group showed thicker and more trabeculae than the PT group at both weeks 4 and 12 (yellow arrows indicate the PT scaffold, white arrows indicate new bone, green arrows reveal new vessels). The 10% GMPT group showed the best osteogenesis and angiogenesis ability.
