Figure 5From: Secreted frizzled related proteins inhibit fibrosis in vitro but appear redundant in vivoDownstream signaling in alveolar epithelial cells after SFRP1 and FRZB stimulation. Western blot of protein extracts from total A549 cell lysates, stimulated with TGFβ1 and SFRP1 (A) or FRZB (B), labeled with antibodies against total β-catenin and active β-catenin.Back to article page
