Fig. 6From: Positive effect on spinal fusion by the combination of platelet-rich plasma and collagen-mineral scaffold using lumbar posterolateral fusion model in ratsHistological images of 12-week specimens from each group upon Masson’s trichrome staining (original magnification, × 40). a PRP group. b PPP group. c Control group. The specimen from the PRP group revealed more abundant new bone formation with matured fusion mass between the transverse process. The specimens from the PPP group and the control group showed residual unabsorbed scaffolds at the fusion bed. TP transverse process, BM bone marrow, G granules of mineral carrierBack to article page
