Healing of Bone Defects in Pig’s Femur Using Mesenchymal Cells Originated from the Sinus Membrane with Different Scaffolds

Figure 2

Hematoxylin and eosin staining of histological micrographs from paraffin-embedded scaffolds implanted in the femur of pigs at 2 and 4 weeks. Asterisks () represent the new bone formation and F corresponds to the fibroblastic reaction while I represents the inflammatory reactions. New bone formation was detected in groups implanted with scaffolds along with the hMSSM cells, in comparison with the control group with scaffolds alone. Magnification is 40x.
