Detailed explanation-1: -Opponents argue that the research is unethical, because deriving the stem cells destroys the blastocyst, an unimplanted human embryo at the sixth to eighth day of development. As Bush declared when he vetoed last year’s stem cell bill, the federal government should not support “the taking of innocent human life.”
Detailed explanation-2: -Embryonic stem cells might also trigger an immune response in which the recipient’s body attacks the stem cells as foreign invaders, or the stem cells might simply fail to function as expected, with unknown consequences. Researchers continue to study how to avoid these possible complications.
Detailed explanation-3: -Cons of the stem cell therapy include: Adult stem cells are hard to grow for long period in culture. There is still no technology available to generate adult stem cells in large quantities. Stimulated pluripotent cells normally do not have any p method of maintenance and reproducibility.
Detailed explanation-4: -To acquire the inner cell mass the embryo is destroyed. Risk to female donors being consented.
