From: Different responses to mechanical injury in neonatal and adult ovine articular cartilage
The morphological assessment of injury/normal tissue and hierarchical clustering analysis of genes expression. A. The model of articular cartilage injury. Articular cartilage explants were dissected onto a 2 × 2 mm2 grid (horizontal and vertical at 2-mm intervals). B. Histomorphometric comparison of isotropic articular cartilage structure in the ovine neonate and anisotropic structure in adults. C. Histomorphometric comparison of injured neonatal and adult articular cartilage. D. The resulting gene trees were grouped (samples/conditions) together based on the similarity of their expression profiles. The dendrogram shows the relationships among the expression levels of conditions.
