Stem cells are undifferentiated cells of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. They can be used to help create new medicines, can help cure diseases, and to generate new cell types, and they can help with infertility in women. Even though stem cells can help with infertility, stem cells should not be used to clone humans or to decrease the diversity of the gene pool but to help people with diseases or to cure diseases.
Embryonic stem cells were first discovered in 1981 by Sir Martin Evans. He discovered them at Cardiff University in the UK, while researching mice. He and a colleague grew the embryonic stem cells in cell cultures until they were able to isolate them. He and a colleague grew the embryonic stem cells in cell cultures until they were able to isolate them. These transgenic mice are considered vital to today 's medical research. The availability of these cultured stem cells eventually made possible the introduction of specific gene alterations into the germline of mice. These transgenic mice were used as experimental models to find cures for human illnesses.
Cloning is the creation of a genetically identical organism to another organism. The first known case of using stem cells to clone an organism was in 1885 when Hans Adolf Edward Dreisch used artificial embryo twinning to make two “twin” sea urchins. Artificial embryo…
