They constructed a vessel by seeding cultured bovine aortic ECs, SMCs, and adventitial fibroblasts on a collagen-coated thin Dacron mesh scaffold (. Human bladder SMC suspension spun at 2500 rpm with porous PGA scaffolds reportedly has greater seeding efficiency than static or spinner flask techniques and has led to more homogeneous deposition (.

C.K.O. Synthetic polymer materials that are biocompatible, non-immunogenic, and degradable are also being explored for use as scaffolds, including polyglycolic acid (PGA), polycaprolactone (PCL), poly-L-lactide (PLLA), and mixtures thereof. Cdh5/VE-cadherin promotes endothelial cell interface elongation via cortical actin polymerization during angiogenic sprouting. Prevascularization of a fibrin-based tissue construct accelerates the formation of functional anastomosis with host vasculature. Although vascular cells can contribute paracrine factors and have regenerative capacity, merely delivering a dispersed mixture of ECs to the host tissue has shown limited success at forming vasculature or integrating with the host vasculature (.

Nat Med 9(6):685–693, Maton A (1994) Human biology and health, 3rd edn. One of the main issues in this approach is the limited viability of transplanted cells because ... Collagen-fibronectin gels containing Bcl-2–transduced human umbilical vein endothelial cells (Bcl-2-HUVEC) implanted in the abdominal walls of immunodeficient mice form mature microvessels invested by host-derived smooth muscle cells (SMC) by 8 weeks. generated ECs from adipose-derived stromal cells, transfected them with adenoviral vector carrying the endothelial nitric oxide synthase (eNOS) gene, and seeded the ECs onto decellularized human saphenous vein scaffolds (. 2019 Aug;3(8):1900089. doi: 10.1002/adbi.201900089. Although the clinical demand for bioengineered blood vessels continues to rise, current options for vascular conduits remain limited. To minimize contamination during the weeks of tissue culture required to produce an arterial prosthesis, a sterile incubator system was developed.

The ability to withstand physiologic pressures without employing a synthetic mesh within the scaffold, however, remained a mystery until L’Heureux et al. Pericytes and perivascular fibroblasts are the primary source of collagen-producing cells in obstructive fibrosis of the kidney. 2015 Aug;9(8):861-88. doi: 10.1002/term.1697. Most of these procedures are in small calibre (<6 mm) vessels, for which synthetic graft materials are not generally suitable. Biophys J 94(1):273–285. Part of Springer Nature.

Tubular scaffolds have been specially designed for culturing small calibre arteries in vitro. Here we explore recent bioengineering advances in creating functional blood macro and microvessels, particularly featuring stem cells as a seed source. Harnessing the regenerative functions reported in ECs derived from adult stem cells and iPSCs offers the promise of improving TEBV patency.
