Figure Lengend Snippet: Overexpression of BST2 mediates cell adhesion between esophageal squamous cell carcinoma (ESCC) cells and mesenchymal stem cells (MSCs) in direct co-culture. A , C , E , G , I , and K: Immunofluorescence staining of TE-9 ( A and G ), TE-10 ( C and I ), and TE-15 ( E and K ) cells was conducted to detect epithelial cell adhesion molecule (EpCAM; red), fibroblast activation protein (FAP; green), and BST2 (blue). The nuclei of the cells were counterstained with DAPI (white). B , D , F, H, J , and L: The numbers of TE-9 ( B and H ), TE-10 ( D and J ), and TE-15 ( F and L ) cells attached to MSCs were counted in accordance with EpCAM expression. A – F: Experiments were performed in triplicate and repeated at least three times. B , D , F, H, J , and L: Two-sided t -tests were performed for the statistical analysis of parametric data. Data are expressed as means ± SEMs ( B , D , F, H, J , and L ). ∗ P < 0.05, ∗∗ P < 0.01, and ∗∗∗ P < 0.001. Scale bars = 50 μm ( A , C , E , G , I , and K ). oeBST2, BST2 overexpression vector; oeNC, negative control vector.
Article Snippet: Human bone marrow–derived MSCs were obtained from ATCC (PCS-500-012; Manassas, VA) and cultured in low-glucose Dulbecco's modified Eagle's medium (DMEM; Fujifilm Wako Pure Chemical Corp.) supplemented with 10% FBS and a 1% penicillin‒streptomycin‒amphotericin B suspension under identical incubation conditions.
