Compatibility of hydrogel extracts in endothelial cell growth medium with endothelial cells. GelA-Hep and GelB-Hep extracts resulted in higher cell viabilities compared to the viability (100 %) of control cells cultured in standard endothelial cell growth medium (100 %, p < 0.05), while Alb-Hep and GM5A5-HepM5 extracts showed similar viabilities to the control (p > 0.1).
