Smooth muscle cell adhesion in surface-modified three-dimensional copolymer scaffolds prepared from co-continuous blends.

29 Sep 2009 In this article, tissue-engineering scaffolds were fabricated from P(epsilon-CL-co-D,L-LA)-PEG-P(epsilon-CL-co-D,L-LA) copolymers using co-continuous blends with polystyrene as the porogen phase. By means of static annealing and following extraction ... Read more...

Endothelial nitric oxide synthase is up-regulated in the umbilical cord in pregnancies complicated with intrauterine growth retardation.

30 Aug 2009 BACKGROUND: NO and NO synthases (NOS) play an important role in the physiology of the fetomaternal blood circulation, although their expression in pathological conditions is unclear. Intrauterine growth retardation (IUGR) is a disorder most probably ... Read more...

Development of decellularized human umbilical arteries as small-diameter vascular grafts.

30 Aug 2009 OBJECTIVE: Developing a tissue-engineered small-diameter (<6mm) vascular graft for reconstructive surgery has remained a challenge for the past several decades. This study was conducted to develop a decellularized umbilical artery and to evaluate ... Read more...

Technical information about 'Umbilical Arteries'

Definition: Specialized arterial vessels in the umbilical cord. They carry waste and deoxygenated blood from the FETUS to the mother via the PLACENTA. In humans, there are usually two umbilical arteries but sometimes one.
