For your main post, address all of these topics:

1. Where do embryonic stem cells come from? Meaning do they come from embryos (fertilized eggs) taken from women or do they come from unfertilized eggs? Are there any other current or potential future sources of stem cells (Do we have to use embryonic stem cells?)?

2. What embryonic stage are these cells in (cleavage, gastrulation, organogenesis, or fetal growth) and how many (cell numbers) are we talking about?

3. Compare and contrast how embryos/embryonic cells are used in artificial reproductive technologies (ART or in vitro fertilization) versus embryonic stem cell therapy. What is the ultimate objective of ART vs. embryonic stem cell therapy?

4. How does embryonic stem cell therapy fit with your definition of life and death? Does it differ when we speak about ART vs. embryonic stem cell therapy? If I have embryonic stem cell therapy and those embryonic stem cells have my DNA in them, are those embryonic stem cells, my embryonic stem cells now growing in me, living or have they been destroyed? Must we now redefine what is life?

During this 2-week discussion, you should compose a main post early in the first week. Write at least a 300-word main post addressing all of the above topics.
