CDH11 and rheumatoid arthritis: In the SL, RA exhibited a clearly elevated cell count (P < 0.0001; Figure 1C) and an increased percentage of pPDGFRαβ+CDH11– cells (P = 0.019; Figures 1D,E), but no differences were noted in the percentages of pPDGFRαβ-CDH11+ or pPDGFRαβ+CDH11+ cells (Figures 1D,F,G).
