Figure 5. CPC differentiation and tube formation as a function of molecular weight of heparin and exogenous TGFβ1 loading.

Figure 5

Representative confocal microscopy images of uptake of Ac-LDL by the differentiated endothelial cells after 12 days of culture in heparin-containing HyA hydrogels (0.03Wt% heparin). Network formation was depending on both molecular weight of heparin (LMWH, UMWH, HMWH) and TGFβ1 loading in HyA hydrogel. Ac-LDL stained red, and cell nuclei counterstained blue.
