Researchers use stem cells to regenerate the external layer of a human heart
January 11, 2017
A process using human stem cells can generate the cells that cover the external surface of a human heart—epicardium cells—according to a multidisciplinary team of researchers.


"In 2012, we discovered that if we treated human stem cells with chemicals that sequentially activate and inhibit Wnt signaling pathway, they become myocardium muscle cells," said Xiaojun Lance Lian, assistant professor of biomedical engineering and biology, who is leading the study at Penn State. Myocardium, the middle of the heart's three layers, is the thick, muscular part that contracts to drive blood through the body.

The Wnt signaling pathway is a group of signal transduction pathways made of proteins that pass signals into a cell using cell-surface receptors.

Another stem cell breakthrough that will save lives....Science is humanities tool to help its self.
 
I suppose that is the case for an adolescent. To someone approaching 3/4 of a century, it looks like this research is going to lead to ways of extending our lives with our own cells, maybe in my lifetime.
