Fig. 2From: Juvenile idiopathic arthritis fibroblast-like synoviocytes influence chondrocytes to alter BMP antagonist expression demonstrating an interaction between the two prominent cell types involved in endochondral bone formationProtein expression of BMP antagonists: chordin, noggin, follistatin, and gremlin. JFLS significantly overexpress chordin (a) and noggin (b) when compared to Ch (p < 0.05, t-test) as determined by ELISA on cell media supernatants. CFLS exhibit a significant decrease in follistatin when compared to untreated Ch (c) while gremlin remained unchanged in FLS when compared to Ch (d)Back to article page
