Induced Pluripotent Stem Cell‐Derived Small‐Diameter Vascular Grafts: Scaffold Design, Immune Engineering, and Clinical Translation
Small‐diameter vascular grafts (≤ 6 mm) remain a critical unmet need in cardiovascular surgery, as autologous vessels are unavailable in up to 30% of patients requiring coronary or peripheral bypass. Induced pluripotent stem cells (iPSCs) have emerged as a transformative cell source for tissue‐engineered vascular graft...
