sFRP3 and DKK1 Regulate Fibroblast-Like Synoviocytes Markers and Wnt Elements Expression Depending on Cellular Context.

CONCLUSION: Our results confirm the involvement of Wnt signaling in FLS transformation and show that two inhibitors of the same cascade can regulate differently the same elements and that a single inhibitor can initiate signaling depending on cellular context.
