Figure 6.

Expression of α-smooth muscle actin (α-sma) upon stimulation with transforming growth factor (TGF)-β or synovial fluid (SF) in combination with bone morphogenetic protein (BMP)-7. BMP-7 treatment of healthy FLSs inhibited the induction of α-sma mRNA by SF16 and SF17 in FLS from all donors, Horizontal lines indicate the median; diamonds indicate FLSs from individual subjects. * indicates P < 0.05.
