Figure Lengend Snippet: Figure 5. STAT3 directly regulates attachment, spreading, migration, proliferation, and profibrotic signaling in 10T1/2 cells (A) Scheme for STAT3 activation using synergistic activation mediators (SAMs) and activation mutants (STAT3-C). (B–F) Immunostaining for (B) pSTAT3 (green), (C) pSMAD2 (green), (D) collagen 1, (E) fibronectin, and (F) a-SMA (green) on STAT3-activated 10T1/2 cells. Scale bars represent 10 mm. Intensity of staining for pSTAT3, pSMAD2, collagen 1, fibronectin, and a-SMA were normalized with cell numbers and plotted in com- parison with control (ctrl) cells (n = 3). p values are shown above the bars as determined by two-tailed unpaired t test. (G) Transwell migration of 10T1/2 cells in STAT3-activated cells. Scale bars represent 50 mm. Cell area normalized to cell number was calculated by CellMask, and fold change was plotted in comparison with control cells (n = 3). Total number of migrated cells was counted on the lower side of the polycarbonate membrane by counting the nuclei (n = 3). p values are shown above the bars as determined by two-tailed unpaired t test. (H) Proliferation of Stat3 WT and KO 10T1/2 cells as assayed by BrdU incorporation assay for 5 days. Percent change was calculated in comparison with day-1 Stat3 WT cells (n = 3). p values are shown above the bars as determined by two-tailed unpaired t test. (I) Adherence assay as shown by staining for F-actin (red) of Stat3 WT and Stat3 KO 10T1/2 cells at 1 h after plating. Scale bars represent 10 mm. Intensity of F-actin normalized to total cell number was calculated, and fold change were calculated in comparison with Stat3 WT cells (n = 3). p values are shown above the bars as determined by two-tailed unpaired t test. (J) Spreading assay as shown staining for F-actin (red) of Stat3 WT and Stat3 KO 10T1/2 cells at 3 h after plating. Scale bars represent 10 mm. Cell area of F-actin normalized to total cell number and fold change were calculated in comparison with Stat3 WT cells (n = 3). p values are shown above the bars as determined by two-tailed unpaired t test.
