Researchers cite progress in efforts to address concerns about embryo destruction and human cloning. October 17, For seven years, scientists have tiptoed through an ethical minefield in their quest to see if unique cells in human embryos might some day be harnessed to treat disease. Now two independent teams of researchers say they have harvested these cells, called embryonic stem cells, from mice using methods they hope may avoid the ethical morass - if the approaches can be made to work with humans. Their results, appearing Monday on the website of the journal Nature, follow a study published in August that examined yet a third tack toward harvesting embryonic stem cells in a less controversial way. Together, these efforts represent a bid to break the stem-cell impasse in the lab rather than in the courts or the halls of Congress.
A more ethical way to harvest stem cells? Scientists are in hot pursuit.

Researchers hope stem cells will one day be effective in the treatment of many medical conditions and diseases. Stem cells have been called everything from cure-alls to miracle treatments. Some unscrupulous providers offer stem cell products that are both unapproved and unproven. The facts: Stem cell therapies may offer the potential to treat diseases or conditions for which few treatments exist. They have the potential to repair, restore, replace, and regenerate cells, and could possibly be used to treat many medical conditions and diseases. But the U.
Back to Stem cell and bone marrow transplants. A stem cell or bone marrow transplant is a long and complicated process that involves 5 main stages. Before a stem cell transplant can be carried out, you'll need a series of tests and examinations to ensure you're healthy enough for the procedure to be carried out. Transplants tend to be more successful in people who are in good general health, despite their underlying condition. If you have cancer, you may also need to have a biopsy.
Embryonic stem cells are derived from embryos that develop from eggs that were created through the in vitro fertilization process. These eggs are then donated for research purposes with the informed consent of their donors. Women do not have abortions to harvest their embryonic stem cells, nor do any providers sell fetal tissue for these cell lines to develop. Human embryonic stem cells come from a transference of cells from a preimplantation-stage embryo in a laboratory culture dish.
