Figure Lengend Snippet: Gene expression and protein exposure of cell surface proteins in MCF7 upon stimulation with TGFβ. (A) Heatmap representing normalized gene expression of different genes ( Y ‐axis) in different samples treated or not treated with TGFβ at the different cell densities ( X ‐axis). Normalization was performed by fixing the first replicate of non‐treated cells (NT) at 20 000 cells per cm 2 to 100%. Statistical significance between NT and cells treated with TGFβ inside each plating density condition was considered. Yellow boxes highlight the genes emerged as significantly different between treated and non‐treated cells. (B) Bars representing relative gene expression of ITGAV (Integrin‐αν/CD51) and LGALS3 n = 3 replicates. Δ C t were calculated using GAPDH as housekeeping. (C) Bars representing the mean fluorescence intensity (MFI) of CD51 and Galectin‐3 exposure on MCF7 cells plated at 20 000 and 60 000 cells per cm 2 . n = 3 replicates. (D) Bars representing the % of MCF7 positive to both CD51 and Galectin‐3 (CD51 + /Galectin‐3 + ) of cells plated at 20 000 and 60 000 cells per cm 2 . n = 3 replicates. (E) Representative flow cytometry histograms of CD51 + and Galectin‐3 + with (Blue) and without (Green) TGFβ treatment at 20 000 cells per cm 2 . n = 3 replicates. (F) Representative flow cytometry counter plot of CD51 + and Galectin‐3 + with (Blue) and without (Green) TGFβ treatment in cells plated at 20 000 cells per cm 2 . n = 3 replicates. Data are expressed as mean ± SD. Significance of data differences was established using unpaired two‐way ANOVA test with multiple comparisons, * P < 0.05, ** P < 0.01 and *** P < 0.001.

Article Snippet: For each experimental condition, 0.2 × 10 6 cells were labeled with 1 : 50 CD51 (CD51 Antibody, anti‐human, REAfinity, Miltenyi Biotec, Bergisch Gladbach, Germany) and Galectin‐3 (Galectin‐3 Antibody, anti‐human/mouse, REAfinity, Miltenyi Biotec) for 20 min at room temperature in the dark.
