Figure Lengend Snippet: (A) Expression of αSMA and vimentin in fibroblasts (hTERT-hNOFs and CAFs) mono-cultured and co-cultured with OSCC YD10B cells for 48 h. Cell lysates were prepared, and then Western blot were performed. (B) Cells grown in the presence or absence of YD10B OSCC cells. After 24h, the cells were harvested and detected mRNA expression of IL-6 and IL-8. (C) After 24h, conditioned medium was collected and the secretion levels of IL-6 and IL-8were measured by ELISA. The results were normalized for total protein and expressed as pg/mg of protein. This assay was performed in independent triplicate repeats (* p < 0.05; Mann-Whitney U test). (D) Representative images are shown to observe OSCC cells (YD10B and YD38) invaded toward stromal proportion with or without fibroblasts (hTERT-hNOFs and CAF#1) in 3D culture conditions. The mixture of each fibroblast and collagen was put into Mill-cell and grown for 14 days. Thereby, the rafts were fixed, embedded in paraffin, sectioned and stained using hematoxylin and eosin. (200x magnification, Scale bar: 100 μm, respectively). (E) SA-β-Gal assay was performed and representative microscopic pictures (a) mono-cultured hTERT-hNOFs (left, top), (d) hTERT-hNOFs, co-cultured with YD10B OSCC cells (right, top), (b) CAF#1 mono cultured (left, middle) and (e) co cultured with YD10B OSCC cells (right, middle) and (c) CAF#2 mono cultured(left, bottom) and (f) co cultured with YD10B OSCC cells (right, bottom) are shown at 72 h (magnification: 200X, scale bar: 2.0 mm). Enlarged images are shown in the bottom of each left.

Figure Lengend Snippet: (A)Cell size was measured on hTERT-hNOFs mono-cultured and co-cultured with HEK and OSCC cells for 3 days. ZEN 2012 software program was used (mono cultured, n = 30; with HEK, n = 23; with YD10B, n = 21; with YD38, n = 20; CAF#1, n = 22; CAF#1(with YD10B), n = 22; CAF#2, n = 16; CAF#2(with YD10B), n = 21) (* p < 0.05, ** p < 0.01, *** p < 0.001; Student t test). CAFs were used to compare cellular size in fibroblasts, respectively. Average of cellular size is shown as CAF#1, 5.74 x 10 9 nm 2 ; CAF#1 (with YD10B), 1.03 x 10 10 nm 2 ; CAF#2, 7.12 x 10 9 nm 2 and CAF#2 (with YD10B), 8.22 x 10 9 nm 2 (* p < 0.05, ** p < 0.01, *** p < 0.001; Mann Whitney U test). (B) All immunofluorescence microscopy experiments were performed on cultured cell after 3 days. DAPI(blue), Phalloidin(red) and Merged staining are shown in mono-cultured hTERT-hNOF(first panels) and hTERT-hNOF co cultured with HEK (second panels), YD10B OSCC cells (third panels) and YD38 OSCC cells (fourth panels), Scale bar, 50μm. The rectangular boxes are shown as enlarged sections to observe the F-actin assembly in left lower part.

Figure Lengend Snippet: (A) Fluorescence microscope was used to check the expression of EGFP on cultured cell after transfection with pcDNA4-HisMaxB-YAP1 and YAPS127A, Scale bar, 200μm. (B) The YAP, p-YAP(S127) and αSMA protein expression was identified in all transfected cells (empty-, WT-YAP-, YAPS127A transfected hTERT-hNOFs) by Western blot. (C) Immunofluorescence images were shown in WT-YAP1- and YAPS127A-hTERT-hNOFs. Merged stained Images (DAPI(blue), F-actin(Phalloidin)(red), YAP(green))are shown. Scale bar, 50μm. The bar graph indicates the distribution of YAP in WT-YAP1- and YAPS127A-hTERT-hNOFs. It was analyzed by Image J software program (WT-YAP1-hTERT-hNOFs, n = 40; YAPS127A-hTERT-hNOFs, n = 40) (*** p < 0.001; Student t test). (D) The representative images show gel contractility by the fibroblasts. Histogram shows mean value ± SD (n = number of gels (Empty, 3; WT-YAP, 3; YAPS127A, 3), assessed over multiple experiments (* p < 0.05; Mann Whitney U test). (E) Histogram shows elastic modulus of matrix remodeled by fibroblasts, respectively. Each data point represents a single measurement, (n = 3, respectively) measurements in total. Line and error bars indicate mean value ± SD. (F-G) Representative images showed the (F) migration and (G) invasion of OSCC cells (YD10B and YD38) cultured with each of fibroblasts, which were transfected with Empty-, WT-YAP-, YAPS127A-transfected hTERT-hNOFs). Quantification of OSCC cells (YD10B and YD38) migration toward lower chamber is shown as bar graphs. Each assay was performed in independent triplicate repeats (* p < 0.05; Mann-Whitney U test).
