Synergistic Effects of FGF-18 and TGF-β3 on the Chondrogenesis of Human Adipose-Derived Mesenchymal Stem Cells in the Pellet Culture

Figure 5

Immunohistochemical staining for type II collagen (ColII) expression in ADSC pellet induced to chondrogenic differentiation for 5 weeks: (a) control; (b) TGF-β3; (c) FGF-18; (d) FGF-18 + TGF-β3. Increased levels of type II collagen expression in pellet culture containing FGF-18 and TGF-β3 were detected by immunohistochemistry.
