“…Un des objectifs majeurs de ces constructions hybrides est en effet de présenter, à terme, au contact du sang, une surface cellulaire non thrombogène [51]. En ingénierie vasculaire, des résultats cliniques probants sont rapportés avec des biomatériaux (dégradables ou non) associés -préa-lablement à leur implantation -à des cellules autologues dans la réalisation de pontages [34], de constructions vasculaires totalement autologues [35], ou dans la chirurgie des cardiopathies congénitales [36]. Selon les cas, les cellules ensemencées sont soit matures soit immatures et, dans ce cas, elles se différencieront in situ .…”

“…The first commercially available tissues included skin substitutes and cartilage replacements (Chung and Burdick, 2008;Priya et al, 2008;Jaklenec et al, 2012). More recently, bladder analogs (Atala et al, 2006) and urethral segments (Atala et al, 1999;El-Kassaby et al, 2003;Raya-Rivera et al, 2011) have been successfully implanted into patients, and artificial blood vessels (Shin'oka et al, 2001;L'Heureux et al, 2007;McAllister et al, 2009;Olausson et al, 2012), trachea (Macchiarini et al, 2008;Baiguera et al, 2010), and corneal tissue (Griffith et al, 2009) have reached clinical trials. In contrast, attempts to fabricate larger functional organs that have more complex cellular organization, such as liver, heart, and kidney, have been unsuccessful (Badylak et al, 2012).…”

The spatial organization of cells is essential for proper tissue assembly and organ function. Thus, successful engineering of complex tissues and organs requires methods to control cell organization in three dimensions. In particular, technologies that facilitate endothelial cell alignment and vascular network formation in three-dimensional tissue constructs would provide a means to supply essential oxygen and nutrients to newly forming tissue. Acoustic radiation forces associated with ultrasound standing wave fields can rapidly and non-invasively organize cells into distinct multicellular planar bands within three-dimensional collagen gels. Results presented herein demonstrate that the spatial pattern of endothelial cells within three-dimensional collagen gels can be controlled by design of acoustic parameters of the sound field. Different ultrasound standing wave field exposure parameters were used to organize endothelial cells into either loosely aggregated or densely packed planar bands. The rate of vessel formation and the morphology of the resulting endothelial cell networks were affected by the initial density of the ultrasound-induced planar bands of cells. Ultrasound standing wave fields provide a rapid, non-invasive approach to pattern cells in three-dimensions and direct vascular network formation and morphology within engineered tissue constructs.

“…Grafts with an average length of 23.2 cm (range 14-30 cm) were implanted into nine patients (one patient was excluded prior to implantation because of gastrointestinal haemorrhage) and were assessed for both mechanical stability and effectiveness during the safety phase (0-3 months) and after haemodialysis was started. While the patency rates were good, it was possible to use the implanted graft for haemodialysis for longer than 12 months in only three patients [9].…”

“…McAllister and colleagues [9] have recently reported the successful implantation of a completely biologic tissueengineered graft for vascular access in ten patients with end stage renal disease receiving haemodialysis. Patency rates at 1 and 6 months were 78 and 60%, respectively.…”
