Effects of P-15 Peptide Coated Hydroxyapatite on Tibial Defect Repair In Vivo in Normal and Osteoporotic Rats

Figure 4

Histological images of defect repairs for both normal and osteoporotic rats. Histology images of defects in normal bone (a, c, e) and osteoporotic bone (b, d, f) are shown. Black arrows indicate residual ABM/P-15 particles inside the defect areas. Size lines in bottom right corner represent 1 mm (a–d) and 250 μm (e and f).
