Fig. 5From: A proteomic analysis of chondrogenic, osteogenic and tenogenic constructs from ageing mesenchymal stem cellsWestern blotting validations of mass spectrometry results. COMP, biglycan and SOD1 abundance were confirmed by western blotting. Representative western blots for tenogenic constructs (a COMP and c biglycan) and chondrogenic constructs (e SOD1). Abundance of each protein is expressed semi-quantitatively (b, d, f) relative to total protein content. Statistical differences were assessed with age in the respective construct and antibody analysis using Mann–Whitney tests. Significant differences represented with p ≤ 0.05Back to article page
