 * (1) When were stem cells first taken from a human embryo?**

//It is controversial, because, in doing so, you kill the embryo.//
 * (2) Why is obtaining stem cells from a human embryo so controversial?**

//Human embryos used in stem cell research have always been and still are taken from fertility clinics after the mother and father of the embryo decided not to have the baby. They were going to be killed whether or not they were used for research.//
 * (3) What was/is the source of human embryos for stem cell research?**

//Stem cells are cells in the early stages of development (the first few cells to develop) that can turn into any cell type we have.//
 * (4) What is a stem cell?**

//Researchers believe that stem cell research can help with Alzheimer's and Parkinson's disease. They study the diseases in a petri dish and then try and find causes and treatments. They think that they can use stem cells to grow replacement tissue for affected people.//
 * (5) What diseases do we think we could treat with stem cells?**

//It started when he put an udder cell inside of an egg and the egg turned it back into a stem cell. Dr. Thompson and Shinya Yamanaka of Kyoto University (independently) both succeeded to mimic what that egg did. They both found that all they had to do was add four genes.//
 * (6) Dr. Thomson is in the news again because he has turned ordinary skin cells into stem cells. How did he do this?**
