Figure 3From: Intrinsic multipotential mesenchymal stromal cell activity in gelatinous Heberden’s nodes in osteoarthritis at clinical presentation Differential gene expression analysis. Hierarchical cluster analysis of quantitative polymerase chain reaction data from culture-expanded Heberden’s node, synovial fluid, osteoarthritic femoral canal bone marrow, osteoarthritic femoral head bone marrow, and normal iliac crest bone marrow-derived multipotential stromal cells together with fibroblasts. Expression levels are normalized to HPRT 1, where black is 1, red is greater than 1, green is less than 1, and grey is below detection.Back to article page
