I'd rather believe true science than anything written in the Washington Times, that right wing publications................read the facts!:::::::Adult Stem Cells vs. Stem Cells from Fertilized Eggs There are several types of stem cells, including those that are derived from fertilized eggs and those derived from adult tissue. To summarize the important differences between the two types: Stem cells from fertilized eggs have the ability to grow infinitely in the laboratory. Adult tissue stem cells are unable to foster substantial growth in the lab. Stem cells from fertilized eggs have the ability to grow into any type of cell or organ in the body. Adult tissue stem cells appear to have a much more restricted path for development, limiting their usefulness in therapies for diseases. As reported in the news media, researchers at the University of California at Los Angeles claim in a recently published study in the journal Tissue Engineering to have isolated adult stem cells from human fat (adipose) tissue. While the finding has potential importance, it also presents significant scientific problems as it relates to stem cell research. The study acknowledges that “it is not conclusive” that human fat tissue contains stem cells; and it goes on to state that the various differentiated cells observed may be due to a number of other factors other than the presence of stem cells. Recent news media reports about the possibility of extracting a kind of stem cell from placentas are based on a press release from the biotech firm Anthrogenesis Corporation; but the assertions presented in the release have not been peer reviewed, independently authenticated, or published in a scientific journal. No such placental cells have been found in animal tissues, and many scientists feel that it is likely that the placental cells in the study were contaminated by blood or other marrow-like stem cells. Eighty Nobel laureates recently sent a letter to President Bush indicating that “it is premature to conclude that adult stem cells have the same potential as embryonic stem cells.” Scientists believe that stem cells from fertilized eggs have the most promise to cure devastating diseases.
