“…Biomaterials adapted for vascular tissue engineering include animal-derived biopolymer gels such as collagen [6], fibrin [7–9], or composites [10]; biodegradable polymers such as polylactic acid, polyglutamic acid, polycaprolactone, polyurethanes, and their copolymers or composite structures [11–18]; and decellularized natural tissues [19–26]. The assembly of cell-populated haemodialysis access grafts from extracellular matrix (ECM) proteins secreted by autologous cells, with no foreign biomaterial, is currently one of the most advanced arterial tissue engineering technologies [27].…”

Collagen and elastin networks contribute to highly specialized biomechanical responses in numerous tissues and species. Biomechanical properties such as modulus, elasticity, and strength ultimately affect tissue function and durability, as well as local cellular behavior. In the case of vascular bypass grafts, compliance at physiologic pressures is correlated with increased patency due to a reduction in anastomotic intimal hyerplasia. In this report, we combine extracellular matrix (ECM) protein analogues to yield multilamellar vascular grafts comprised of a recombinant elastin-like protein matrix reinforced with synthetic collagen microfibers. Structural analysis revealed that the fabrication scheme permits a range of fiber orientations and volume fractions, leading to tunable mechanical properties. Burst strengths of 239–2760 mm Hg, compliances of 2.8–8.4%/100 mm Hg, and suture retention strengths of 35–192 gf were observed. The design most closely approximating all target criteria displayed a burst strength of 1483 ± 43 mm Hg, a compliance of 5.1 ± 0.8%/100 mm Hg, and a suture retention strength of 173 ± 4 gf. These results indicate that through incorporation of reinforcing collagen microfibers, recombinant elastomeric protein-based biomaterials can play a significant role in load bearing tissue substitutes. We believe that similar composites can be incorporated into tissue engineering schemes that seek to integrate cells within the structure, prior to or after implantation in vivo.

“…5 The use of bovine carotid artery (BCA) heterograft for hemodialysis access was first reported by Chinitz et al 6 and was used extensively by many centers in the 1970s. [7][8][9][10][11][12][13][14][15][16] However, with the advent of ePTFE grafts later that decade, BCA grafts fell out of favor despite the lack of data to account for the change in paradigm. 16 With the efficient and effective endovascular techniques now available to manage complications along with improvements to BCA manufacturing, we felt revisiting BCAs as AV conduits for hemodialysis would be worthwhile.…”

“…The use of BCA biological grafts began in the 1970; however, their use declined with the development of grafts made from synthetic polymers such as ePTFE. [10][11][12][13][14][15] Although ePTFE conduits remain the dominant AVG in use today, resurgence in the use of biologic grafts has been observed. This retrospective study presents an extensive investigation of differences in outcomes between BCA and ePTFE vascular access conduits as well as insight into factors limiting graft patency.…”
