'Ghost heart,' a framework for growing new human hearts, could be answer for thousands waiting for new heart
The problem: More than 3,200 people are on the waiting list for a heart transplant in the United States. Some won't survive the wait. Last year, 340 died before a new heart was found. The solution: Take a pig heart, soak it in an ingredient commonly found in shampoo and wash away the cells until you're left with a protein scaffold that is to a heart what two-by-four framing is to a house. Too cool!
