Anti-platelet adhesion and in situ capture of circulating endothelial progenitor cells on ePTFE surface modified with poly(2-methacryloyloxyethyl phosphorylcholine) (PMPC) and hemocompatible peptide 1 (HCP-1)
2020, Colloids and Surfaces B: BiointerfacesCitation Excerpt :We aim to implement ePTFE, not only in the prevention of acute thrombosis by PMPC grafting for short-periods, but also in accelerating endothelialization for long term blood compatibility. There are two approaches to improve the endothelialization: EC pre-seeding [12,13] and intensification of endothelial progenitor cell (EPC) capture [14]. The EC pre-seeding method has limitations.
Sphingosine-1-phosphate improves endothelialization with reduction of thrombosis in recellularized human umbilical vein graft by inhibiting syndecan-1 shedding in vitro
2017, Acta BiomaterialiaCitation Excerpt :Several biomolecules have been used to pre-coat bypass grafts to enhance EC attachment. Herring et al. [50] coated vascular prostheses with various extracellular matrix proteins and blood products to enhance EC retention. Extracellular matrix components including fibrin [51], collagens [52–54], elastin, fibronectin [53–55], laminin [56], and aptamers [57] are often used to pre-coat tissue-engineered grafts.

2008, Journal of Surgical ResearchCitation Excerpt :Mixed results have been reported from clinical trials [5–11]. Some persistent problems with this technique are improving initial seeding efficiency of the cells to the biomaterial and maintaining endothelial cell adhesion following exposure to flow [3, 12]. Endothelial cells cultured under static conditions will attach, migrate, and proliferate on the very same biomaterials that cells will detach from under flow conditions [4].
In vitro evaluation of electrospun silk fibroin scaffolds for vascular cell growth
2008, BiomaterialsCitation Excerpt :The extraction of PEO did not significantly affect the morphology or diameter of the fibers. Good retention of vascular cells on seeded grafts is a critical issue for clinical transplantation [19,20]. The assessment of the retention of endothelial and smooth muscle cells on ESFS in vitro can provide initial confirmation of the utility of this new system.
In a pig model ePTHE grafts will sustain for 6 weeks a confluent endothelial cell layer formed in vitro under shear stress conditions
2003, European Journal of Vascular and Endovascular SurgeryCitation Excerpt :Autologous saphenous vein is the preferred conduit for femoro-distal bypass but is often unavailable.1 The patency rates of small diameter ePTFE grafts are disappointing2-10 partly because of the absence of an endothelial cell lining.11-16 However, the artificial seeding of ePTFE grafts with autologous harvested endothelial cells failed to improve patency in vivo,17-19 possibly because such cells fail to adhere on to the graft under normal blood flow conditions.20,21
