Using lasers to stimulate bone marrow stem cells can improve blood flow
Millions of Americans buy Plavix from a Canadian online pharmacy to help reduce their risk of experiencing a stroke or heart attack.
Millions of Americans buy Plavix from a Canadian online pharmacy to help reduce their risk of experiencing a stroke or heart attack. Such adverse cardiovascular events can lead to a dangerous thinning of the heart walls and a decreased ability to efficiently pump blood throughout the body. However, using laser-treated stem cells extracted from bone marrow could help restore the function and health of this important organ, according to Tel Aviv University scientists.
Lead author Uri Oron from the Department of Zoology has developed a non-invasive procedure that involves the administration of laser energy to bone marrow stem cells. Performing this technique hours after a heart attack can reduce scarring by as much as 80 percent.
Oron, who published the paper in the journal Lasers in Surgery and Medicine, explained that activating the stem cells enabled them to use their healing qualities to stimulate the growth of new arteries. This improved blood flow throughout the body.
"After we stimulate the cells with the laser and enhance their proliferation in the bone marrow, it's likely that more cells will migrate into the bloodstream," he stated. "The cells that eventually reach the heart secrete growth factors to a higher extent, and new blood vessel formation is encouraged."
