The heart makers
Educational only: videos on MedicalVideos.com are for general information and are not medical advice. Always consult your own doctor about your health.
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. At the Massachusetts General Hospital in Boston, Harald Ott and his team are reusing the scaffold that nature provides. They’re stripping away all the living cells from dead hearts, before filling in the leftover matrix with healthy new cells. 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.

This video presents research on making a working human heart, following work at Massachusetts General Hospital by Harald Ott and his team. It explains that scientists can turn stem cells into beating heart cells but need a scaffold to organize them into a 3D heart, and describes stripping living cells from dead hearts and filling the leftover matrix with healthy new cells, with possible use for parts of the heart such as the aortic root and valve for transplant.
