Histological analyses at 4 weeks in vitro chondrogenic culture of hMSCs on small and large-pore scaffolds. H&E staining shows that cells grew throughout the whols scaffolds in both small (125–250 μm) (A) and large-pore (425–600 μm) (B) scaffolds (Scale bar: 200 μm). Alician blue staining showed a denser glycosaminoglycan matrix deposition in small (C) as compared to large-pore (D) scaffolds (Scale bar: 100 μm). Similarly, collagen type II immunohistochemical staining revealed more collaged type II matrix deposition in small (E) than large-pore (F) scaffolds (Scale bar: 100 μm). n=3 for each group.
