1. The Stem Cell Dilemma Zhaoyuan (Zoe) Xi AP Biology P. 1

3. Stem Cell Basics 2 basic types: – Embryonic stem cells – Adult stem cells Can divide & renew themselves for a long period of time Unspecialized Differentiate into other cell types Potential to treat disease/injury

6. The Dilemma “The status of the human embryo and human embryonic stem cell research is a controversial issue as, with the present state of technology, the creation of a human embryonic stem cell line requires the destruction of a human embryo.”

7. The Opponents Mainly conservative pro-life Protestant evangelical and Catholic communities Embryos are human Morally wrong to destroy a human Fertilization is the starting point in life Alternative? Adult stem cells The Supporters Majority of Americans Hold enormous potential for curing/treatments – Embryonic stem cells have greater plasticity Embryos used for research are left over and would otherwise be thrown away Embryos aren’t people
