Prof. Oron, who has long used low level lasers to stimulate stem cells to encourage cell survival and the formation of blood vessels after a heart attack, was inspired to test how laser treatments could also work to heal the heart. He and his fellow researchers tried different methods, including treating the heart directly with low level lasers during surgery, and "shining" harvested stem cells before injecting them back into the body.
But he was determined to find a simpler method. After a low-level laser was "shined" into a person's bone marrow — an area rich in stem cells — the stem cells took to the blood stream, moving through the body and responding to the heart's signals of distress and harm, Prof. Oron discovered. Once in the heart, the stem cells used their healing qualities to reduce scarring and stimulate the growth of new arteries, leading to a healthier blood flow.
To determine the success of this method, Prof. Oron performed the therapy on an animal model. Following the flow of bone marrow stem cells through the use of a fluorescent marker, the researchers saw an increase in stem cell population within the heart, specifically in the injured regions of the heart. The test group that received the shining treatment showed a vastly higher concentration of cells in the injured organ than those who had not been treated with the lasers.
This leads to the important question: What mythology maps well to the summoning of stem cells using lasers? I don't see a fit for Lord Of The Rings. Do you? Which mythology summons legions of good soldiers using a light wand?
Professor Oron says his technique is ready for clinical trials...
