The controversy surrounding embryonic stem cell research is similar to that surrounding the arguments about pro choice. There are those who view conception as the beginning of life. They believe embryos to be human life. Therefore, some consider using embryonic stem cells for research as murder in much the same way as those opposed to abortion view that procedure as murder. Arguments in favor of stem cell research point out that embryos are not viable outside the mother's body. That's why they have to be frozen. Human beings can't be frozen, so how can embryos be human beings? Undoubtedly, the controversy will exist for quite some time.
embryonic stem cells can differentiate into more types of cells
embryonic stem cells can differentiate into more types of cells
The adult stem cells are better than embryonic stem cells in a very few cases. One way they are better is that the adult stem cells can be transplanted back into the adult patient and grown. The body will not reject its own stem cells.
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.
well yes....and no
embryonic stem cells can differentiate into more types of 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.
The umbilical cord has stem cells in it. Baby teeth are another possible source of stem cells.
The use of stem cells is not unethical in and of itself, the ethics component revolves around the source of the stem cells and the concern that fetuses will be produced and intentionally destroyed in order to obtain stem cells.
Embryonic stem cells are used to treat a variety of diseases. Stem cells also help organs and tissues repair themselves.
Stem cells are used for fighting off deadly diseases, and stem cells can help cell growth and reproduction.
Yes, stem cells are active in our bodies all our lives
