The heart is the body's hardest-working muscle. Whether you're awake or asleep, or exercising or resting, your heart is always at work. It pumps blood through arteries to deliver oxygen to organs ...

In addition, this team hopes to eventually “cellularize” the printed heart, or add human heart muscle cells to the structure, to make it beat like the real thing.

German researchers have grown human heart tissue that expresses genes, responds to drugs, and beats just like the real thing.

One month after an experimental procedure to transplant the heart of a genetically modified pig into a patient with end-stage heart disease, doctors say the heart is functioning on its own and ...

Largest human image of the heart grows bigger, breaks Guinness World Record The event would be truly successful when each one of us daily take the 30 minutes exercise challenge and spread the ...

Researchers are using stem cells to grow new hearts that match a transplant recipient's original heart, so they won't be rejected. Their goal is to have a supply of organs on hand and do away with ...

Surgeons have successfully implanted an artificial titanium heart in the chest of a human patient that is powered by the same ‘maglev’ technology used in the creation of high-speed trains.

Viewers control the heart image using a joystick and special 3-D glasses linked to infrared cameras that gauge a person’s position relative to the screen.

Doctors at the University of Maryland Medical Center say the transplant showed that a heart from a genetically modified animal can function in the human body without immediate rejection.

To develop the microengineered human heart tissue-on-a-chip, researchers begin with human induced pluripotent stem cells grown in the laboratory. Such cells are able to develop into nearly any type of ...

What Happened: A Maryland hospital completed the first transplant of a pig heart into a patient in a last-ditch effort to save the man’s life, according to the Associated Press.
