Quantification of the amount of captured EPCs and macrophages on HA-based hydrogels at different times. (a) Quantification of cell attachment on CD34 antibody immobilized gels. EPC attachment was found to be significantly higher after 1 h seeding compared to 5 min time point. After 1 h, though, there was no statistical difference in terms of adhered EPCs with respect to increasing time. (b) Comparison of the amount of captured EPCs and macrophages on HA hydrogels at 3 h. No significant difference was observed for macrophage attachment at different antibody concentrations for the same time point. In addition, macrophages adhered significantly less on the hydrogels compared to EPCs (error bars: ±SD, * p < 0.05, and ***p < 0.001).
