First 3D Print-Heart Unveiled By Israel's Scientists, Is It Feasible?

Israel's Scientists unveiled a 3D print of heart by using human vessels and tissues. It's "first and major medical success" by Israel, which will lead to the possibilities of transplants.

Although it is a distant one, scientists hope that one day humans will be able to produce suitable hearts for transplantation and also prepare a patch to regenerate defective hearts.

Unveiled by Tel Aviv University’s researchers

The size of 3-D printed heart formed by researchers at Tel Aviv University is similar to the heart of a rabbit. "For the first time in medical history, someone has successfully engineered and printed the whole heart with cells, blood vessels, ventricles, and chambers," said Tal Dvir, who led the project. People have been able to print the 3D structure of a heart in the past, but not with the cells or with blood vessels.

The 3-D printed heart shown at Tel Aviv University does not work yet. It needs to mature in a bioreactor, where electrical and mechanical signals will be used to synchronously contract the cells, a process that will take about a month's time.

Israel's Researchers also need to find out how to produce more and larger cells so that they can ultimately print the human shape heart, which contains billions of cells.

Dvir estimates, it's likely to lead the 3D-printed human heart in hospitals within a decade. But not everybody can take benefit of 3-D printed heart, citing the moral implications - such as whether it will widen the gap between rich and poor, and whether supernatural heart or other mutations can also be created.
