Experts develop heart muscles made from human cells


A team of researchers at the University of Minnesota, America, succeeded in printing human heart muscles in a laboratory using stereo printing techniques, which may help save the lives of thousands of heart patients, given that heart disease is the main cause of death for more than sixty thousand people in the United States only annually.

Researchers reported that they used a type of stem cell, which can be converted to any other type of human cell, in addition to a mixture of proteins, as an ink for the stereoscopic printer.

The muscle size printed by the researchers is 1.5 cm, and it has been specifically designed to fit into the size of the rat’s chest cavity, for further studies.

The study team confirmed that the new cardiac muscle that has been manufactured can be used to study cardiac function and health problems that it may be exposed to.
