For years mankind has dreamed of emulating some other species. Rejuvenation of appendages has long been a dream. A surgeon normally takes out a longer section of vein than is needed for a heart bypass. The Bristol team (research, by Paolo Madeddu, Professor of Experimental Cardiovascluar Medicine and his team in the Bristol Heart Institute (BHI) at the University of Bristol, is published in the journal Circulation.) successfully isolated stem cells from leftover veins that patients had agreed to donate. In tests in mice, the cells proved able to stimulate new blood vessels to grow into injured leg muscles. Professor Madeddu and his team are now beginning to investigate whether the cells can help the heart to recover from a heart attack.
However, the stem cell usage remains pretty much in the research field with a lot of 'if'. Click here.
Unfortunately, from the year 2000 to 2008, GW Bush, President of the United States, chose to put the views of religious zealots before scientific study so that there was essentially a moratorium on productive research, slowing the field down for those years. Additionally, many top scientists moved out of the United States to places where they could continue their research, further slowing down gains here.
"Professor Peter Weissberg, Medical Director of the BHF, said: "Repairing a damaged heart is the holy grail for heart patients. The discovery that cells taken from patients' own blood vessels may be able to stimulate new blood vessels to grow in damaged tissues is a very encouraging and important advance. It brings the possibility of 'cell therapy' for damaged hearts one step closer and, importantly, if the chemical messages produced by the cells can be identified, it is possible that drugs could be developed to achieve the same end."
