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.
What else can I help you with?
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 do adult stem cells currently have fewer uses in therapeutic cloning that embryonic stem cells?
Adult stem cells have more limited differentiation potential compared to embryonic stem cells, making them less versatile for therapeutic cloning. Additionally, adult stem cells are often harder to manipulate in the lab and may not replicate as easily as embryonic stem cells. However, adult stem cells have the advantage of being less likely to be rejected by the recipient's immune system, which can be a benefit in certain therapeutic applications.
How are adult stem cells better then embryonic stem cells?
Adult stem cells are better than embryonic stem cells in some ways because they have less risk of immune rejection, as they can be collected from the patient's own body. Additionally, the use of adult stem cells avoids the ethical concerns surrounding the use of embryonic stem cells. Adult stem cells have also shown promising results in various treatments and therapies.
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.
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 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.

A kid eats 73 less than a adult.

What is a sentence using the word yellow marrow?
