Scientists believe stem cells, unspecified cells that will eventually mature into specialized cells (brain cells, liver cells, etc), can lead to a medical revolution. Stem cells have the ability to regenerate cells and tissues, offering possible treatment for numerous diseases. Stem cells have two main varieties, adult and embryonic. Adult stem cells are derived from human tissues like bone marrow, skin, and placenta. Embryonic stem cells are derived from human embryos. Scientists prefer embryonic stem cells over adult stem cells because embryonic stem cells are more versatile. Although some may argue that embryonic stem cell research is unethical, many of the embryos are willingly donated. Embryonic stem cell research is expensive, but the potential financial reward would be vast. Because of the amazing economical and medical potential of embryonic stem cells, the United States government should not ban embryonic stem cell research.
