  abstract  = {Despite advancements of modern medicine, the number of patients with the the end-stage kidney disease keeps growing, and surgical procedures to establish and maintain a vascular access for hemodialysis are rising accordingly. Surgical access of choice remains autogenous arteriovenous fistula, whereas approach "fistula first at all costs" leads to failure in certain subgroups of patients. Modern synthetic vascular grafts fail to deliver long-term results comparable with AV fistula. With all that in mind, this work has an aim of developing a new alternative vascular graft, which can be used for hemodialysis access using the methods of TE, especially electrospinning technique. It is hypothesized that electrospun scaffold, made of PCL and collagen type I may assemble mechanical properties similar to native blood vessels. Seeding such electrospun scaffolds with human microvascular endothelial cells (hmvECs) and preconditioning with shear stress and continuous flow might achieve sufficient endothelial lining being able to resist acute thrombosis. One further topic considered on-site infections, which represents one of the most spread complications of dialysis therapy due to continuous needle punctures. The main hypothesis was that during electrospinning process, polymers can be blended with antibiotics with the aim of producing scaffolds with antimicrobial properties, which could lead to reducing the risk of on-site infection on one side, while not affecting the cell viability.},
