Strategies to counteract adverse remodeling of vascular graft: A 3D view of current graft innovations

Frontiers in Bioengineering and Biotechnology, 2023
Vascular grafts are widely used for vascular surgeries, to bypass a diseased artery or function as a vascular access for hemodialysis. Bioengineered or tissue-engineered vascular grafts have long been envisioned to take the place of bioinert synthetic ...

Surface modification of decellularized bovine carotid arteries with human vascular cells significantly reduces their thrombogenicity

Journal of Biological Engineering, 2021
Background Since autologous veins are unavailable when needed in more than 20% of cases in vascular surgery, the production of personalized biological vascular grafts for implantation has become crucial.

The application of tissue-engineered fish swim bladder vascular graft

Communications Biology, 2021
Bai et al. employ a fish bladder-derived decellularized matrix for the engineering of vascular grafts. The authors show that rapamycin-coated bladder-derived vascular grafts can be implanted as an interposition graft in rats, and that these vascular ...
