Figure 6: Cartilage-specific staining of repaired regions.

From: Repair of osteochondral defects with in vitro engineered cartilage based on autologous bone marrow stromal cells in a swine model

Figure 6

Negative staining for Safranin-O and collagen type II was observed in the repaired tissue of the 2-week and blank groups. Repaired tissues in the cartilage defect regions of the 4- and 8-week groups showed continuous and strongly positive staining for Safranin-O and collagen II, but negative staining for these markers in bone defect regions. Black arrows indicate repaired regions.
