Research on Stem Cells Shows a Ray of Hope
A year after President Barack Obama lifted limitations on research into embryonic stem cells and promised billions in new stimulus money for it, researchers are nearly giddy with enthusiasm about the advancement in the field. They're confident that stem cells will be capable of treating or may someday providing a complete cure for people with heart disease, diabetes, spinal cord injury and other disorders.
This excitement, however, is not generated by stem cells that have been harvested from human embryos. Instead, researchers are coming to believe they can get results that would be approximately as good from adult stem cells that is taken from the patient's individual bone marrow or belly fat, and even full-fledged adult cells from muscle tissue or skin.
Dr. Joshua Hare, Director of the Interdisciplinary Stem Cell Institute at the University Of Miami Medical School stated that adult stem cells are more flexible than they had thought. The embryonic stem cell may not be the one that proves to be really successful in the actual therapy.
In order to treat a patient with heart problems or who suffers heart attack may be benefited more with an adult stem cell.
By now, at the UM Medical School, adult stem cells have already been injected around a patient's heart so as to help heal a heart attack, and adult cells are being applied around injured spinal cords with the hope of restoring its movement.
This is news will definitely fill in heart patients, a ray of hope, because it will cure their heart attacks and save a number of lives, further giving joy o those families and people who could lose their loved one to this disease.
Another new development exhilarating researchers is the stimulated pluripotent adult stem cell. Scientists at Harvard and in Japan took cells from the skin on a patient's arm and genetically reprogrammed them to be almost as supple as embryonic stem cells, without destroying an embryo. They expect to use them one day to build up total human organs, cell by cell.
