Figure 9: In vitro inhibition of HUVEC migration by sFLT-1. The optical density of migrated cells was measured at 490 nm. Results indicate migration of sFLT-1 treated cells versus GFP treated or untreated cells. Each data point is presented as mean ± SEM. Considerable decrease in cell migration was observed as value (0.001) was less than the chosen significance level (0.05).
