NGF staining by flow cytometry. PBMC of (a) healthy controls (HC) and (b) synovial fluid mononuclear cells (SFMC) from spondyloarthritis (SpA), and (c) rheumatoid arthritis (RA) patients were first stained with surface markers (CD3 and CD14) and permeabilized in order to enable intracellular detection of nerve growth factor (NGF). The cells were analysed by flow cytometry after setting lymphocyte (left column) and monocyte (right column) gates according to forward scatter vs side scatter properties of the cells. Dot plots of one representative individual of each group are shown.
