Figure Lengend Snippet: GC cells increase collagen 1 expression in fibroblasts and collagen increases proliferation of GC cells (A) Expressions of Col1A1, Col1A2, and ACTA2 mRNA in mouse gastric cancer (GC) cells (T3-2D), human GC cells (MKN45, MKN7, and NUGC4), mouse fibroblast cells (MEF), and human fibroblast cells (YS-1 and FEF3) are shown. All cells were analyzed by quantitative RT-PCR analysis. Data are expressed as the mean ± SD ( n = 3). (B) Expression of Col1A1 and Col1A2 mRNA in MEF (upper) and YS-1 (lower) cells after incubation with serum-free medium (SFM) as a control and conditioned medium (CM) of each GC cell type for 4 days. Cells were analyzed using quantitative RT-PCR analysis. Data are expressed as the mean ± SD ( n = 3). (C) Representative images of immunocytochemical staining of collagen 1 and α-SMA in MEF (left) and YS-1 (right) after incubation with normal medium and CM of each of the GC cells for 4 days. SFM was used as a control. The area index for each staining was evaluated by ImageJ software. Data are expressed as the mean ± SD ( n = 3). Scale bars, 50 μm. (D) Cell proliferation of T3-2D and MKN45 cells with and without 10% collagen stimulation for 72 h. Data are expressed as the mean ± SD ( n = 5). (E) Representative cellular morphological images of T3-2D and MKN45 cells with and without 10% collagen 1 stimulation for 72 h. Scale bar, 100 μm. ∗ p < 0.05, ∗∗ p < 0.01, ∗∗∗ p < 0.001, ∗∗∗∗ p < 0.0001.
