PA-YK-NO coated stents support endothelial cell viability (A). At 7 days, HUVECs seeded on PA-YK-NO coated stents attach, spread, and remain viable. Scale bar = 500 μm. (B) Uncoated control stent implanted in rabbit iliac artery, 4 week time point. (C) PA-YK-NO coated stent implanted in rabbit iliac artery at 4 weeks.
