Nature video presents: How do you make a working human heart? Scientists can turn stem cells into beating heart cells, but getting them to organize into a 3D heart requires a scaffold.

In this video, Brendan Maher finds out how the technique could be used to develop parts of the heart, like the aortic root and valve, for transplant.

Another group of scientists, next to Dr Doris Taylor and her team, is working on this exciting project and the question is – when first hearts will be ready? That is big news, considering the fact heart failure is number one reason of death in most countries worldwide.
