Figure 4From: Hedgehog/Gli promotes epithelial-mesenchymal transition in lung squamous cell carcinomasShh/Gli signaling down-regulates E-Cadherin expression. Immunofluorescent staining of E-Cad (green) in lung SCC H2170 cells treated with Gli-I, vismodegib, and recombinant Shh proteins. DAPI (blue) was used to stain nuclei of those cells.Back to article page
