Fibrin and Collagen Differentially but Synergistically Regulate Sprout Angiogenesis of Human Dermal Microvascular Endothelial Cells in 3-Dimensional Matrix

Figure 1

In vitro three-dimensional human angiogenesis model for assaying cell invasion, migration, and sprout angiogenesis formation of human dermal microvascular endothelial cells (HDMEC) (a). Step I: HDMEC are cultured on the surface of microcarrier beads to generate EC-beads. Step II: EC-beads are embedded in fibrin gel, collagen gel, or fibrin/collagen gel, with or without the presence of angiogenesis factor.
