Adhesion of AGS and NUGC3 gastric cancer cells to vascular endothelial cells. (a) Representative images of the adhesion of tumour cells (AGS, upper; NUGC3, lower) to monolayer-cultured HUVEC stimulated by 1.0 µg/mL of LPS and 100 µg/mL of MP. Scale bars are equal to 500 µm. (b) Number of tumour-binding cells (AGS and NUGC3) to monolayer-cultured HUVEC stimulated by 1.0 µg/mL of LPS and 100 µg/mL of MP. Data are means ± standard error (n = 6, each group); *P < 0.05. (c) Representative images of the adhesion of tumour cells (AGS, upper; NUGC3, lower) to monolayer-cultured HHSEC stimulated by 1.0 µg/mL of LPS and 100 µg/mL of MP. Scale bars are equal to 500 µm. (d) Number of tumour-binding cells (AGS and NUGC3) to monolayer-cultured HHSEC stimulated by 1.0 µg/mL of LPS and 100 µg/mL of MP. Data are means ± standard error (n = 6, each group); *P < 0.05. (e) Representative images of the adhesion of tumour cells (AGS, upper; NUGC3, lower) to monolayer-cultured HUVEC depleted of E-selectin stimulated by 1.0 µg/mL of LPS. Scale bars are equal to 500 µm. (f) Number of tumour-binding cells (AGS and NUGC3) to monolayer-cultured HUVEC depleted of E-selectin stimulated by 1.0 µg/mL of LPS. Data are means ± standard error (n = 6, each group); *P < 0.05. (g) Invasion assay of of AGS and NUGC3 gastric cancer cells co-cultured with HUVEC stimulated by 1.0 µg/mL of LPS and 100 µg/mL of MP. Data are means ± standard error (n = 5, each group); *P < 0.05.
