Figure 4

Characterization of loaded and non-loaded constructs following the hypertrophic culture phase. The panels depict histological Safranin-O staining, immunohistochemical staining for collagen type-II, alizarin red (AR) staining and immunohistochemical staining for collagen type-X, and bone sialoprotein (BSP), respectively (n = 4). Loaded constructs show a higher degree of maturation as compared to non-loaded constructs. Scale bar = 1 mm (valid for all panels).
