The main controversy is whewn stem cells are harvested from aborted fetuses, or when an egg is fertilized in a laboratory for the sole purpose of harvesting stem cells.
Stem cells can also be gotten from umbilical cord blood after a baby is born.

One argument against stem cell research is the ethical concern regarding the use of human embryos. Some individuals and groups believe that using embryonic stem cells involves the destruction of potential human life, which goes against their moral or religious beliefs.
Similarities: Both adult and embryonic stem cells have the potential to develop into different cell types in the body. They are both utilized in research to study cell behavior and potential therapies. Differences: Embryonic stem cells are derived from embryos, while adult stem cells are found in various tissues in the body. Adult stem cells have a more restricted potential to differentiate into specific cell types compared to embryonic stem cells. Ethical issues are often raised with the use of embryonic stem cells due to the source of their derivation.
embryonic stem cells can differentiate into more types of cells
One concern with stem cell research is the ethical issue surrounding the use of embryonic stem cells, as the extraction process involves the destruction of human embryos. This raises ethical questions about the beginning of human life and the rights of embryos.
