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 4

(a) Collagen type I staining of the medial condyle showing the defect region with regenerative tissue following the different interventions. The slides of the upper row were stained with an isotype control antibody; the slides of the lower row were stained using the specific antibody. Red color indicates positive staining. (b) Collagen type II staining of the medial condyle showing the defect region with regenerative tissue following the different interventions. The slides of the upper row were stained with an isotype control antibody; the slides of the lower row were stained using the specific antibody. Red color indicates positive staining. (c) Collagen type X staining of the medial condyle showing the defect region with regenerative tissue following the different interventions. The slides of the upper row were stained with an isotype control antibody; the slides of the lower row were stained using the specific antibody. Red color indicates positive staining.
