Placental arteries (umbilical arteries) are blood vessels. In placental animals, the blood vessels which develop within the placental cord carrying relatively deoxygenated blood from the embryo/fetus to the placenta. In humans, there are two placental arteries continuous with the paired internal iliac arteries (hypogastric arteries) arising off the dorsal aortas. At birth, this vessel regresses and form the remnant medial umbilical ligament.

Human umbilical vein ECs were obtained from the umbilical arteries of newborns, kindly provided by the Women and Children Healthcare Centre of Chengdu. ECs were cultured in M199 medium containing 10% FBS in a humidified atmosphere of 95% air and 5% CO2 at 37 °C. The culture medium was changed every 2 days and the cells were passaged through trypsinization. After culturing for 1 and 3 days, samples were washed three times using PBS, and fixed in 2.5% glutaraldehyde solution for 12 h. After dehydrating, dealcoholizing and critical point drying, the samples were sputter-coated with gold, and imaged through scanning electron microscopy (SEM, Quanta200, Philips, Amsterdam, Netherlands).
