Analysis of total synovium-derived cell population with four-color flow cytometry: representative sample . Cells are stained with 7-aminoactinomycin (7-AAD), CD45- fluoro-isothiocyanate (FITC), one phycoerythrin (PE)-conjugated antibody and one allophycocyanin (APC)-conjugated antibody or their isotypes. (a) Dye exclusion of debris and dead cells in forward scatter (FSC)/FL3 in contour plot (top) and dot plot (bottom). G1 gates for live cells. (b) Subgating of CD45-negative stromal (G2) and CD45-positive (G3) hematopoietic cell populations based on isotype staining with IgG1-FITC and cell granularity (side scatter). (c) Quantification of <t>CD34-expression</t> and CD90-expression within the stromal fraction. The gating for CD90-positive cells was based on IgG1-PE specifically measured on CD45-negative cells. (d) Quantification of CD14, CD3, and CD20-expression within G3. The gating for CD20-positive cells was performed on IgG1-PE measured on total cells. (e) Plots showing CD105-APC, CD73-PE, CD146-PE, and human leucocyte antigen (HLA)-DR-PE staining in the stromal fraction with their appropriate isotype controls.

Detection and quantification of CD271 and CD34 in digests and cultured cells . (a) Plots of two representative samples. The CD45-negative fraction is gated in G1. Within this fraction, a portion of cells is positive for CD271 or CD34. Double positive cells are sometimes well clustered (lower plot). To be uniform, the quantification is performed using quadrant analysis. (b) Data points representing the expression levels in percentage positivity on the cell surface detected in the fresh digests. (c) Plots of cultured cells after staining. Cells are gated according to scatter properties (G1), viability (G2) and the signal for the markers is compared with the isotype controls. No double positive cells are recognized here. 7-AAD = 7-aminoactinomycin; APC = allophycocyanin; FITC = fluoro-isothiocyanate; FSC = forward scatter; PE = phycoerythrin; SSC = side scatter.
