Human Fat-Derived Mesenchymal Stem Cells Xenogenically Implanted in a Rat Model Show Enhanced New Bone Formation in Maxillary Alveolar Tooth Defects

Figure 5

Immunohistochemistry. Representative images depicting immunohistochemical staining (Nove Red) of decalcified bone samples with OPN (a), FN (b), and CD34 (c) are shown. Histological sections from rats treated with Gelfoam® alone and Gelfoam®+hMSCs for 4 weeks are shown. The anatomical regions are labelled. Black dotted lines indicate region of interest illustrated in the 10x magnification. Note the areas of relatively organized pattern of staining in the hMSC-treated defects.
