Figure Lengend Snippet: FIGURE 6. Consequences of MMP2 or TIE2 inhibition on HRMEC angiogenic activities. (A) In vitro Matrigel-based angiogenesis assay illustrating the tube formation capabilities of MMP2, TIE2, and NC siRNA-transfected HRMECs under normoxic conditions. (B) Quantita- tive data reflecting the number of nodes and cumulative tube length from the in vitro Matrigel-based angiogenesis assay (n = 3/group). (C) Representative imagery from the transwell assay assessing endothelial migration potential. (D) Quantitative assessment of migratory cells derived from transwell assays (n = 3/group). (E) Under hypoxic conditions, the in vitro Matrigel-based angiogenesis assay highlights the tube formation proficiency of MMP2, TIE2, or NC siRNA-transfected HRMECs. (F) Quantitative evaluation of the in vitro Matrigel assays under hypoxia (n = 3/group). (G) In the context of hypoxia, the transwell assay unveils the migratory capabilities of HRMECs post-transfection with MMP2, TIE2, or NC siRNA. (H) Quantitative data detailing the number of migrating cells from the hypoxic transwell assays (n = 3/group). Scale bar: 200 μm.
