Fig. 2From: Dynamic Hyaluronan drives liver endothelial cells towards angiogenesisEffect of HA treatment on tubule formation of ECs. The influence of HA on vascular tubule formation of ECs are shown with DIC images of Matrigel assay. Murine ECs with HA treatment (right panel) were found with more growing vascular sprouts in comparison to untreated ECs (left panel) after 18 h (a, b) and 48 h (c, d) respectively. e The quantification of tubules (indicated with arrows) were measured per microscopic field after indicated time points. *p < 0.05; **p < 0.01Back to article page
