Vet-grown rat heart could save millions of lives

Scientists used a heart matrix created from newborn rat’s heart and injected muscle and endothelial cells to form a new heart. Then it was stimulated electrically.

“We've got a scaffold, nature knows how to create a scaffold better than you and I. We took nature's tools, gave them the cells, and began to build an organ,” said Doctor Doris Taylor, head of the research team.

The same technology could be used to produce other organs as well, Taylor added.

The research was conducted as an attempt to find new treatments for heart diseases.

Medicine experts say lab-grown organs that suit the patient’s immune system could be a good alternative to donor organ transplants and artificial replacement organs.
