Researchers at the University of California, the U.S. managed in the laboratory to grow a miniature human heart from stem cells. A-body diameter is only half a millimetre, but it has a camera like this ventricle of the heart. Scientists are going to use the mini-heart for the testing of new drugs and the study of heart disease.

"Our model is the first step to building a heart that relies on self-organization of stem cells without the use of external supporting materials," said Zhen MA, specialist of the University.

Already conducted the first experiment: in the mini-heart introduced a dose of sleeping pills "Thalidomide", which was popular in the middle of the last century, and then in the grown body began violations and deviations in development.
