Stem Cells (the Disadvantages and Advantages)

Evaluation

So, overall both embryonic and adult stem cells replace the faulty cell with a healthy cell, so the person is well again. They also both may produce a cancer cell instead of a healthy one, which is a risk. Embryonic stem cells are easy to extract from the embryo and can produce any type of cell, but the downside of using embryonic stem cells is that the embryo is destroyed when the cell is removed, this is an ethical issue because some people believe that embryos have a right to live. The body also recognises the cells as 'different' and will reject them without the use of drugs. With adult stem cells the embryo is not destroyed, so it isn't an ethical issue. If the adult stem cell is taken from the person to be treated, it will not cause rejection in the body. However adult stem cells are difficult to find and extract from the tissue and can only produce a few types of cell.
