3-D printing, bioinks create implantable blood vessels

A biomimetic blood vessel was fabricated using a modified 3-D cell printing technique and bioinks, which were formulated from smooth muscle cells from a human aorta and endothelial cells from an umbilical vein. The result ...

New 3-D printing technique for biomaterials

A new way of 3-D printing soft materials such as gels and collagens offers a major step forward in the manufacture of artificial medical implants.

Lab-made blood vessels: Mechanics matters

Biodegradable tubes that turn into living blood vessels once implanted in the human body. In an imaginary, modern remake of Fantastic Voyage, Isaac Asimov would probably navigate his submersible through the folds of our cardiovascular ...

Study suggests T. rex had an air conditioner in its head

Tyrannosaurus rex, one of the largest meat-eating dinosaurs on the planet, had an air conditioner in its head, suggest scientists from the University of Missouri, Ohio University and University of Florida, while challenging ...

Tropical sea snake uses its head to 'breathe'

Humans use a snorkel and fish have gills. Now researchers have found a sea snake which uses a complex system of blood vessels in its head to draw in extra oxygen when it dives and swims underwater.

Peptide hydrogels could help heal traumatic brain injuries

Traumatic brain injury (TBI)—defined as a bump, blow or jolt to the head that disrupts normal brain function—sent 2.5 million people in the U.S. to the emergency room in 2014, according to statistics from the U.S. Centers ...

A 'switch' that regulates traffic across blood vessels

NUS scientists have discovered a control mechanism that regulates the traffic of cells and substances across blood vessels. This effect can have significant impact on cancer metastasis.

Blood vessel

The blood vessels are the part of the circulatory system that transport blood throughout the body. There are three major types of blood vessels: the arteries, which carry the blood away from the heart, the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back towards the heart.
