Figure 4From: Quantitative proteomics reveals regulatory differences in the chondrocyte secretome from human medial and lateral femoral condyles in osteoarthritic patients Representative biopsy images and experimental line-up. Saffranin O staining of the LM lateral femur condyle (A), LM medial femur condyle (B), representative HM lateral femur condyle (D) and representative HM medial femoral condyle (E). Schematic view of the experimental procedure where chondrocytes were extracted from lateral and medial femoral condyle of the same knee joint, labeled in culture, incubated for medium conditioning and analyzed with MS (C).Back to article page
