Figure 2

Endothelial network formation in unconstrained COL/FIB/HA composite hydrogels at day 7. Upper panels show representative images of network structures in COL/FIB matrices at indicated HA concentrations (both entire construct and magnified subsections are presented). Graph shows quantification of total network length at each HA concentration. n = 4. *Statistical significance (p<0.05) against 0 mg/ml (pure collagen/fibrin).
