CD271+ cells in established synovial fluid (SF) cultures. a Percentage of CD271+ quantified by flow cytometry in passage 3 SF cultures from normal (n = 4), osteoarthritis (OA; n = 8), or rheumatoid arthritis (RA; n = 5) synovial biopsies. b Progressive reduction of CD271+ cells in SF cultures from OA synovial membranes (n = 3) throughout passages 0–5.
