Figure 7From: Intrinsically superparamagnetic Fe-hydroxyapatite nanoparticles positively influence osteoblast-like cell behaviourHistological evaluation of the in vivo implanted HA and FeHA granules. Toluidine Blue, Acid Fucsin and Fast Green staining shows similar histocompatibility for both biomaterials 4 weeks after implantation (n = 6). A) HA control group, B) FeHA group.
