First 3D Printed Heart has Human cells, Vessels

Scientists claim to have made the first ever 3D-printed heart with human tissue and blood vessels.

Although the organ is only the size of a cherry and cannot pump blood, experts said its creation is a ‘major medical breakthrough’.

The heart is believed to the be the first ever to have been printed with cells, blood vessels and chambers.

Although the hearts will need more work before they can pump blood, the scientists hope to begin trials using them within a year.
