Heart failure is caused by injury to the myocardium (the heart muscle), resulting in irreversible loss because this tissue cannot regenerate itself. Now, Bargehr and collaborators have managed to derive epicardial cells and growth factors from human embryonic stem cells that can regenerate damaged heart muscle.

In these experiments in the field of regenerative medicine, conducted in rats, it was found that the improvements to heart function persisted for three months. From a bioethical point of view, we must highlight the difficulty presented by this subject, since human embryonic stem cells were used to produce the heart cells (see more HERE).
