1. There is a great deal of controversy concerning stem cell research, so I wanted to learn what all the hubbub was all about.
2. Hopefully one day, stem cell research will be able to re-grow any new organ or body part, and perhaps also undo the damage done by any disease and aging.
3. First, there are embryonic stem cells attained from blastocysts.
4. A blastocyst is basically an egg after it has been fertilized yet before an embryo begins forming in the egg.
5. Second, there are adult stem cells too.
6. Adult stem cells are not naturally as versatile or available as embryonic stem cells; therefore, they are currently not as useful for research.
7. The controversy over stem cells is from the destruction of fertilized human eggs when harvesting embryonic stem cells (…).
8. For instance, infertility doctors typically create several embryos for women who are unable to naturally become pregnant (…).
9. (...) then the doctor chooses the best fertilized egg to implant into the woman (…).
10. Instead of these embryonic eggs going to waste, they are sometimes used for stem cell research.
11. However, many conservative individuals, especially politicians, are trying to make embryonic stem cell research illegal, because they believe it kills human life.
12. On the other hand, the use of adult stem cells is less controversial (…).
13. (...) adult stem cell research is significantly behind embryonic stem cell research because of availability and versatility of adult stem cells.
14. Basically, the United States believes that embryos are not people to prevent abortions, yet the government gives preferential treatment to pre-embryos.
15. Furthermore, if these stem cells are going to be destroyed anyways, it is best to use them to possibly help save and improve lives.
