Experiments in a culture dish show that chick heart cells (red) do grow in the scaffold channels (green) at densities similar to those in a living heart (UW)
Although medical advances over recent years have seen the majority of people surviving heart attacks, the damage done to the heart muscle is irreversible. As a result, most patients eventually succumb to congestive heart failure, the most common cause of death in developed countries. Stem cells offer hope for achieving what the human body can’t do: mending broken hearts. Now researchers have built a scaffold that supports the growth and integration of stem cell-derived cardiac muscles cells. The scaffold supports the growth of cardiac cells in the lab and encourages blood vessel growth in living animals.
