Figure 7From: TWEAK and Fn14 expression in the pathogenesis of joint inflammation and bone erosion in rheumatoid arthritisEffect of soluble TWEAK on cell surface RANKL expression by STRO-1 osteoblast subpopulation. Human primary osteoblasts were cultured untreated or treated with rhTWEAK (50 ng/ml) for three days, harvested by collagenase/dispase digestion and stained for STRO-1 and RANKL expression. Stained cells were analysed by FACS. The percentage of cells present in each of the four sub-populations is indicated. Data are presented for two independent donors' cells.Back to article page
