Examples of differentially expressed genes. (A) Relative expression levels of genes differentially expressed between all multipotential stromal cells (MSCs) and fibroblasts (FBs). (B) Relative expression of differentially expressed gene between Heberden’s node (HN)- and synovial fluid (SF)-MSCs compared with bone and bone marrow-derived MSCs from normal and osteoarthritis patients. All cell types were tested in triplicate. OAFCBM, osteoarthritic femoral canal bone marrow; OAFHBM, osteoarthritic femoral head bone marrow.
