Galectin-induced cytokine secretion enhances expression of the endothelial cell surface adhesion molecules, which are responsible for galectin-mediated cancer cell-endothelial adhesion. ( A ) The presence of galectins induces expressions of cell surface adhesion molecules. Human micro-vascular lung endothelial cells were treated with control 1.5 μ g ml −1 BSA (red colour) or 1.5 μ g ml −1 galectins -2 (purple), -4 (brown), -8 (green), a combination of G-CSF (0.25 ng ml −1 ), IL-6 (0.15 ng ml −1 ), GRO α (1 ng ml −1 ), MCP-1 (1 ng ml −1 ) (black) for 24 h before the expressions of the HMVEC surface <t>integrin</t> <t>α</t> <t>v</t> β 1, VCAM-1, CD44 and E-selectin were analysed by flow cytometry.
