3D printed biomimetic flexible blood vessels with iPS cell-laden hierarchical multilayers.

ABSTRACT: Successful recovery from vascular diseases has typically relied on the surgical repair of damaged blood vessels (BVs), with the majority of current approaches involving the implantation of autologous BVs, which is plagued by donor site tissue damage. Researchers have attempted to develop artificial vessels as an alternative solution to traditional approaches to BV repair. However, the manufacturing of small-diameter (< 6 mm) BVs is still considered one of the biggest challenges due to its difficulty in the precise fabrication and the replication of biomimetic architectures. In this study, we successfully developed 3D printed flexible small-diameter BVs that consist of smooth muscle cells and a vascularized endothelium. In the developed artificial BV, a rubber-like elastomer was printed as
