According to WebMd, there are three main disadvantages to using adult stem cells. The first is that adult stem cells are more mature. They have the ability to become numerous types of cells, but a limited amount compared to embryo stem cells which has the potential to cure more diseases. The second major disadvantage is that adult stem cells can be hard to identify. A human body contains billions of cells; when adult stem cells are found, they are usually in small amounts. The third reason is that adult stem cells take a long period of time to grow. Experiments show that when adult stem cells are found, it takes months for the certain type of cell to grow. Embryonic stem cells on the other hand can be made into several types of cells. When they are needed, the doctor will thaw them and they are ready for use.
Potential cures for diseases include:
