Figure 3From: Secreted frizzled related proteins inhibit fibrosis in vitro but appear redundant in vivoDownstream signaling in pulmonary fibroblasts after SFRP1 and FRZB stimulation. Western blot of protein extracts from total MRC5 cell lysates, stimulated with TGFβ1 and SFRP1 (A) or FRZB (B), labeled with antibodies against pSMAD3, total SMAD3, total β-catenin, active β-catenin, and β-actin.Back to article page
