"Firefly" stem cells, that glow, may eventually help doctors heal hearts without actually cutting the patient. Steven Ebert used the same enzymes that make fireflies glow to create stem cells. As "firefly" stem cells grow into heart muscle they become brighter. This enables doctors to track the stem cell because of the brightness of it. Stem cells will morph into the organs in which they are placed but how fast and why is still in question. Ebert's new cells can give the ability to track the cells action with the use of cameras without having to cut into patients.
In my opinion, this is a great discovery because now patients with heart damage will no longer have to wait for a donor. This great discovery will also keep doctors from having to cut their patients. I think it is interesting how scientists have figured out a way to heal damaged hearts with glowing stem cells. Patients with this new stem cell may live longer than people who have to get a whole transplant. This discovery keeps paitents healthier and stronger because they don't have to get them full transplants.
