Nodal Promotes the Self-Renewal of Human Colon Cancer Stem Cells via an Autocrine Manner through Smad2/3 Signaling Pathway
Figure 2
Protein expression of Nodal ligand and its receptors in various human colorectal cancer cell lines. (a–c) Immunocytochemistry showed translation of NODAL (a), ALK-4 (b), and ACTR-IIB (c) in human colon cancer cell lines, including SW480 cells, LOVO cells, and HCT116 cells. Scale bars in (a)–(c) = 10 μm.
