Reinforced Biotubes: Readily Available Regenerative Vascular Grafts
Researchers Cheng, Zhi and Midgley have unveiled reinforced biotubes—bioengineered vascular grafts that combine living cells with nanofibrous reinforcement—to address durability and availability limits of current grafts. The tubes are fabricated in bioreactors, seeded with smooth‑muscle and endothelial progenitor cells, and reinforced via electrospun nanofibers, achieving burst pressures surpassing human saphenous veins. Preclinical animal implants showed rapid endothelialization, no thrombosis or aneurysm, and low immune response. A cryopreservation protocol enables off‑the‑shelf storage, positioning the grafts for emergency and widespread clinical use.
