(WHAS11) - University of Louisville doctors are already using stem cells for research but they're using adult stem cells instead of embryonic stem cells.
U of L doctors are leading the world's first clinical stem cell trial at Jewish Hospital.
That groundbreaking study, announced last month, will use heart patients' stem cells to treat heart disease.
When it comes to embryonic stem cells, President Obama says he wants science to lead, not ideology.
U of L says it respects the beliefs of people who think the use of embryonic stem cells is wrong.
"We certainly respect them, but also respect the beliefs of scientists who are passionately involved in the pursuit of cures for terrible, life-threatening, life-destroying illnesses. At the end of the day, it becomes a matter of law," says University of Louisville's Dr. Larry Cook.
Cook says U of L wants to take a closer look at the new stem cell guidelines and definitions before making any decisions about future stem cell research.
