Most likely because embryonic stem cell research is often associated with another controversial social issue-- abortion. Some (but not all) embryos used in stem cell research have been donated for research, but the donors are clinics which perform abortions. Also, even in cases that did not involve abortion, such as excess embryos from fertility clinics, some opponents of using embryos believe life begins when an egg has been fertilized, so therefore, the embryo represents human life, and to destroy any embryo to do stem cell research is thus immoral. Although not everyone agrees that a fertilized egg is the same as a human being, the pro-life community has been very vocal in opposition, keeping embryonic stem cell research mired in controversy.
On the other hand, extracting adult stem cells does not require destroying an embryo nor does it affect a fertilized egg, so some pro-life supporters feel it is morally preferable to use adult stem cells for research. Unfortunately, adult stem cells are not as helpful to utilize in research because they cannot do some of the things that can be done with embryonic stem cells. Thus, this too is controversial, as scientists and researchers believe they are being hampered in finding cures for diseases because of the religious beliefs of certain people who oppose the use of embryonic stem cells.

∙ 11y agoThe primary controversy with the use of embryonic stem cells is with the source of the cells (very often aborted fetuses) and the concern that any fetus might be generated and aborted for the purpose of using it's stem cells. While stem cells can and are harvested from the umbilicus (usually to be stored for potential use by the
donor in case it is needed once the child matures) many right-to-life groups are
concerned about the life and welfare of an aborted fetus's soul. Since these groups often believe that the soul is present at conception the idea of intentional abortion is murder.
Adult stem cells can be collected without sacrificing the adult.

Which type of stem cell is less controversal?
Adult stem cells are much less controversial. This is because they do not involve embryos at all. However, adult stem cells cannot differentiate into as many different types of cells as the embryonic stem cell (which can become any type).
Why are cells from a blastula ideal to examine mitosis?
Unlike most cells in an adult body, an embryonic mass of cells is always dividing. Most cells in the adult body is quiscent and will not divide unless signals have been given to them to divide, and many cells such as muscle and nerve cells have even lost the ability to divide.
What are the differences between embryo and adult stem cells?
Adult stem cells are harvested from newborn's cord blood or human bone marrow while embryo stem cells come from the inner cell mass of a human embryo. No fetus is killed to use the stem cells, but the embryo cannot function and must be destroyed without a inner cell mass.
Can stem cells change into any other cell?
Yes. Stem cells can change into any other cell, through a process called "differentiation" However, adult stem cells are less likely to do so, as opposed to embryonic stem cells that can differentiate readily
Why does distilled water make your cells explode?
Because it makes it cooler instead of using regular water.

What is difficult about using adult stem cells for regenerative medicine?
The older the subject is, the less capable their stem cells are at being able to diversify into all types of cells.
Why do researchers prefer to use embryonic stem cells in medical research?
One reason researchers prefer to use embryonic stem cells instead of adult stem cells because adult stem cells are often found in limited quantities, are difficult to isolate, and the older the donor, the less stem cells they have.

What is a sentence using the word yellow marrow?
White blood cells are formed in the yellow marrow. Red blood cells are formed in the red marrow. Yellow marrow has a higher concentration of fat.
Why do plant Cells have Cell walls and animal Cells have Cell coats?
The plant's cell wall protects the cell from damage (the plant cells are less fragile than animal cells and less flexible).Plant and bacterial cell walls provide intense strength using cellulosic materials. Some animal cells equally require this same strength yet they utilize a sugar-protein [glycocallyx] cell coat.
