Comparison of Regenerative Tissue Quality following Matrix-Associated Cell Implantation Using Amplified Chondrocytes Compared to Synovium-Derived Stem Cells in a Rabbit Model for Cartilage Lesions

Figure 3

(a) HE (upper row) and Safranin-O (lower row) staining of the medial condyle showing the defect region with regenerative tissue following the different interventions. The red color indicates the presence of glycosaminoglycans. (b) The OARSI score is lower in the lesions treated with amplified chondrocytes compared to negative controls (n.s.: not significant).
