Now, Rich writes, “when Barack Obama ended the Bush stem-cell policy last week, there were no such overheated theatrics.”
It launches curricular reviews and stem-cell initiatives; it raises money, and buys up property (or at least, it used to).
Many women who undergo IVF either discard their leftover embryos or donate them for stem-cell research.
Maybe they would, but this has played absolutely no part in the stem-cell debate.
I am often criticized for previously voting for John Kerry and my support of stem-cell research.
The stem-cell controversy is really about abortion, of course.
Whatever, the result is that the promise of stem-cell research is delayed or unrealized.
stem cell n.
An unspecialized cell that gives rise to a specific specialized cell, such as a blood cell.
|stem cell |
An unspecialized cell found in fetuses, embryos, and some adult body tissues that has the potential to develop into specialized cells or divide into other stem cells. Stem cells from fetuses or embryos can develop into any type of differentiated cells, while those found in mature tissues develop only into specific cells. Stem cells can potentially be used to replace tissue damaged or destroyed by disease or injury, but the use of embryonic stem cells for this purpose is controversial. Also called progenitor cell.
A cell from which a variety of other cells can develop through the process of cellular differentiation. Stem cells can produce only a certain group of cells (as with skin stem cells) or any cell in the body (as with embryonic stem cells).
Note: A major controversy involves the question of whether nonembryonic stem cells should be used for medical purposes.
