The article I chose explains the three different types of stem cells used in research and the treatment of diseases. The three types are adult, umbilical cord, and embryonic stem cells. My article points out that the adult stem cells which are extracted from bone marrow or the peripheral blood system are superior to the other types of stem cells. Adult stem cells are taken directly from the patient’s own body so there is an exact DNA match and the body’s immune system will not reject them. Since the bone marrow is a rich source of stem cells, they are always abundant. My article also states that mice treated for Parkinson’s with embryonic stem cells have died from brain tumors in as much as 20% of cases. In addition, embryonic stem cells stored over time have created abnormalities that create cancer cells. I would argue as the article does that research funds should be devoted to adult stem cell research over embryonic stem cell research as the adult stem cells are more promising in the treatment of diseases of all types.
