An embryonic cell is an unfertilized egg that until fertilized after the 8th week is a fetus. Stem cells are the cells that develop into any human cell tissue. Embryonic stem cell research is using a human embryo and inserting another humans DNA into and then basically cloning another human. When the embryo has another humans DNA it creates a perfect match to the DNA donor's body. Stem cells can be taken from the embryo to grow human organs.
There are many debates about whether an embryo is a human or just a bunch of cells. Some people say "It isn't a human until the fetus has left the mother and taken its first breath". For life to possible a human needs blood and organs. It takes nine months for a human to capable of supporting its self. Embryos lack the capacities that make us human such as, a brain and heart.
Embryos don't have emotions and cannot feel physical pain since they are not a fully developed human. Since they are not humans they have no rights and should not be treated as a human but as a cell and nothing more. There are strong arguments supporting the belief that human life begins when the brain develops and is able to make decisions on its own. The other view point is that they will have the ability to make decisions on their own over time and you should look at the future of the cell.
To think that an embryo is not a human is against many people's moral beliefs including many religions. Catholic Archbishop, Denis Hart said "It's a draconian step. It's a shame to argue that human beings should be treated like lab animals." The catholic Archbishop argues that stem cell research goes against the dignity of...
