After two to five days, the umbilical vein and ductus venosus are completely obliterated; the former becomes the round ligament of liver and the latter becomes the ligamentum venosum.
32.
Within the child, the umbilical vein and ductus venosus close up, and degenerate into fibrous remnants known as the round ligament of the liver and the ligamentum venosum respectively.
33.
On multiple occasions, people have changed this section of text to state that the umbilical arteries carry oxygenated blood to the fetus, and that the umbilical vein carries deoxygenateay.
34.
The umbilical vein catheter is a reliable alternative to percutaneous peripheral or central venous catheters or intraosseous canulas and may be employed in resuscitation or intensive care of the newborn.
35.
Having passed through the umbilical opening, the two arteries, now termed umbilical, enter the umbilical cord, where they are coiled around the umbilical vein, and ultimately ramify in the placenta.
36.
In human umbilical vein endothelial cells ( HUVEC ), translocation of Ang to the nucleus stops after cells reach a specific density, while in HeLa cells translocation continued past that point.
37.
On multiple occasions, people have changed this section of text to state that the umbilical arteries carry oxygenated blood to the fetus, and that the umbilical vein carries deoxygenated blood away.
38.
In the fetus, the normal range differs based on which umbilical vessel is sampled ( umbilical vein pH is normally 7.25 to 7.45; umbilical artery pH is normally 7.18 to 7.38 ).
39.
A study showed that forced expression of calponin 2 in endothelial cells enhanced angiogenic cell migration " in vivo " and anti-sense calponin 2 RNA reduced chemotaxis of human umbilical vein endothelial cells in culture.

So, in 1946, Diamond and Dr . Fred Allen started doing the transfusions through the newborn's large umbilical vein, which remains open for days after birth, using an experimental piece of newly developed plastic tubing.
