Though there is limited ethical debate on adult stem cell research in comparison to embryonic stem cell research, there are still a few challenges. Adult stem cells are present but in very small amounts. By having such a small amount, it can pose problems for identifying and containing a large enough amount of cells needed for therapy. The regeneration of cells is not as successful as those cells in embryonic stem cells they do not reproduce to the same degree. Embryonic stem cells are young and adult stem cells are mature, the adult stem cells contain more DNA abnormalities which can be caused by environment, toxins or errors in DNA replication.
In conclusion it is clear to see the need for adult stem cell research. Researchers and I alike can reason with its benefits and learning more about birth defects and treating such diseases and cancers as Leukemia. I consider myself a reasonably ethical person so I can appreciate the fact that adult stem research does not present a high
