Figure 2. Histological sections: Bone formation and inflammation in pores.
Histological sections from the top region of a PPF/PF-DA polymer alone sample. a) Round and pink tissue is immature bone, light pink tissue layers are fibrous tissue, and dark blue areas suggest inflamed tissue. Bar is 1 mm. b) Magnified image shows rounded pink areas of bone formation (B), dark blue areas of inflamed tissue and patches of small blue inflammatory cells (IF). Bar is 100 µm.
