This color-coding approach was used to identify and purify a rare daughter cell of a master heart stem cell that the researchers then used to make a an actual working heart muscle cell...
...team used a mouse cardiac stem cell to develop a functioning, intact strip of mouse heart muscle, raising the possibility that such cardiac stem cells can have regenerative capacity if manipulated appropriately...
...like Saran Wrap, and when cells are put on top of it, they can be forced into a pattern,” Chien said. “We take cells we have isolated to form strips of functioning muscle. It’s like a Band-Aid for the heart, and cells line up just the way you want them...
Chien said this is the first time someone has been able to make a functional muscle in a mature conformation by facilitating the transition from a pluripotent embryonic stem cell—a cell that has the capacity to differentiate into any other cell type—to heart tissue...

In the heart of the city, the provincial legislature had been festooned with vast posters commemorating the sacrifice of the army officers who lost their lives repelling last weekend's attack on military headquarters in Rawalpindi.
