Comparative Evaluation of Bone Repair with Four Different Bone Substitutes in Critical Size Defects

Figure 3

Photomicrograph of histological sections: (A) histological detailed features of the biomaterials (BIO, BFL, CLN, and LBP) and surrounding tissues in the central region of the defect at 40 days (HE, original magnification 40x); (B) mallory trichrome staining (original magnification 40x). CT: connective tissue; NB: newly bone formed; OLC: osteoblastic line cells. In CLN: (a) Mallory trichrome staining, (b) HE, original magnification 40x.
