J.M.
I am almost hesitant to answer this question for fear of being verbally crucified, however I do have an opinion I am willing to share. Adoption is a wonderful thing, I myself was adopted and raised by wonderful people, and I believe that your consideration is both warrented and unselfish. However, as a mom, if I were to put myself in your shoes, I would worry about the "embryo" and the family that is was given to. Yes, screenings can be done, but people and situations can change, making an ideal one go wrong. I feel very stongly that stem-cell research is completely worthwhile and needed; that if I had the option to help by donating cells to save lives, possibly thousands of lives, then that is the way I would go. I hope this helps, and please to everyone else, we each are entitled to our own beliefs and opinions.
