Adult and embryonic stem cells each have advantages and disadvantages in regard to how they can be used in regenerative therapies (National Institute of Health, 2008). Embryonic stem cells can become any type of cell in the body since they are pluripotent. But according to the National Institute of Health (2008), adult stem cells can only differentiate into the organ in which they came from, which is a huge disadvantage, and a reason why scientists say the embryonic stem cells are much more useful, and have a lot more potential.
