Researchers from the Universities of Toronto and Montreal in Canada have engineered a major piece of the human heart, and it beats normally.
Despite significant progress in recent decades in the study of treatments for cardiovascular disease, almost 18 million people worldwide still pass away from heart problems every year.
An ethical, more precise alternative to current methods might be provided by a tiny working model of a human ventricle, which could pave the way for the creation of novel drugs and therapies as well as for the study of the development of cardiovascular conditions.
A millimeter-long (0.04 inches) vessel was reverse-engineered by researchers from the Universities of Toronto and Montreal in Canada. It not only beats realistically but also pumps fluids much like the muscular exit chamber of a human embryo's heart.
"With our model, we can measure ejection volume – how much fluid gets pushed out each time the ventricle contracts – as well as the pressure ...
