EPCs on Ti surface were stained for PECAM-1 (green) after 3 days in porcine IVC. (A) Scale bar = 200 μm. (B) EPCs additionally showing pre-implantation stain PKH26 (red) and nuclei stained with Hoechst 34580 (blue). Scale bar = 50 μm. (C) Cell nuclei on bare metal control implant surface stained with Hoechst 34580, showing presence of macrophages, T-cells and granulocytes in a non-uniform distribution. Scale bar = 100 μm.
