HUVEC attachment on the surfaces of Blank-PCL and DIP 20% loaded materials 24 and 48 h post seeding. Scale bar = 100 μm (A). HUVEC proliferation inhibition was assessed using a CyQUANT™ NF Cell Proliferation Assay after incubation for up to a total of 48 h, following a prior 24 h period of time allotted to allow for cellular attachment post seeding. The PCL graft without loaded drugs 24 h were set as the control. Error bars represent mean ± SEM (n = 3), p value shown: p < 0.05. (B).
