Embryonic Stem Cells Unnecessary for Medical Progress :: Argumentative Persuasive Topics

Embryonic Stem Cells Unnecessary for medical checkup Progress   Reporting on new research by Dr. Donald Orlic of the subject argona Institutes of Health and others, indicating that braggy bone marrow solution electric cells can care reclaim, and restore function in, damaged embraces Until now, researchers thought that stem cells from embryos offered the surpass hope for rebuilding damaged organs, but this latest research shows that the embryos, which are politically controversial, may not be necessary. We are currently finding that these adult stem cells can function as well, perhaps evening better than, embryonic stem cells, Orlic said.   - Approach may liven heart damage, MSNBC, March 30, 2001 (www.msnbc.com/news/552456.asp)   * * *   Umbilical cords discarded after behave may offer a vast new source of repair material for fixing brains damaged by strokes and other ills, free of the respectable concerns surrounding the use of fetal weave, researchers said Sunday.   - Umbilical cords could repair brains, Associated Press, February 20, 2001   * * *   PPL Therapeutics, the company that cloned bird the sheep, has succeeded in reprogramming a cell -- a apparent motion that could lead to the development of conductments for diseases such as diabetes, Alzheimers and Parkinsons. The Scotland-based group will at once announce that it has turned a cows skin cell into a vanquish heart cell and is close to starting research on humans... The PPL announcement...will be seen as an important step towards producing stem cells without using human embryos.   - PPL follows Dolly with cell breakthrough, Financial Times, February 23, 2001   * * *   Organ-specific adult stem cells appear to display a great deal more plasticity than originally thought. Stem cells isolated from one tissue can differentiate into a variety of unrelated cell types and tissues... These findings arrange the exciting possibility of using bone mar row transplantation to treat a wide variety of disorders, such as stringy dystrophies, Parkinson disease, stroke, and hepatic failure.   - E. Kaji and J. Leiden, Gene and Stem Cell Therapies, Journal of the American Medical Association, February 7, 2001, p. 547   * * *   Since adult bone marrow has recently been found to contain stem cells of antecedently unrecognized plasticity that are able to form a variety of types of cell -- muscle, liver, neural, bone, cartilage, endothelial, and perhaps others -- it may be possible to use marrow stem cells in cytotherapeutic approaches to a wide spectrum of diseases, such as cardiac disorders, muscular dystrophy, liver disease, neurodegenerative conditions, and joint diseases.
