The study has recently been published in the Circulation Research Journal. Earlier they used mice as donors. Apr 02,  · The cold war helps settle a hot debate about how hearts grow. in Stockholm has shown that adult human hearts make new muscle cells, heart cells that can generate cardiomyocytes in culture Author: Monya Baker.

New York, NY—April 4, —Growing human cardiac tissue that behaves like native heart muscle would be transformative for biomedical research, enabling researchers to study human physiology and model heart diseases under fully controlled conditions. While today scientists can grow many tissues, including the heart muscle, from stem cells taken from a small blood sample of any of us, current bioengineered tissues fail to show some of the most critical hallmarks of adult human heart . Jan 10,  · Still, for many years, the accepted belief in the scientific community was that human hearts grow after birth only because cells grow larger. Kühn's work challenges the accepted wisdom and offers.

Apr 29,  · Their study appears in the April 29 issue of Developmental Cell. Arteries form in utero and during development, but can also form in adults when organs become deprived of oxygen — for example, after a heart attack.
