, If anyone of you could help me it would be very nice of you. The Second thing is if there is a homepage existing on which i can see how to write a good analysis.
Greeting Jokinghorse
The first method is about the fusion of brain cells and stem cells. When the two cells fuse, the brain cell convertes into a stem cell. The disadvantage of this proceeding is that two cells have to meet each other. If this is not possible there there will no more stem cells be generated. The advantage of it is that there is only the need of a brain and an embryo. Furthermore, these new stem cells could be implanted into a human’s body. This is the chance to get a big advantage out of it.
The second method includes the gene Nanog which boosts stem cells during the fusion with a brain cell. Nanog makes it safe to gain stem cells, and it is certain that they are created during a fusion. The disadvantage is that it is not natural to let stem cells get boosted by the chemical substance named Nanog. It would be natural if only stem cells and brain cells fused.
All of these techniques have in common that embryos are killed during the procedure. If there were only cells of adult people it would be more acceptable ethically. Scientists think that embryos have the most potential for future therapies which can be considered a helpful discovery.
Nanog is first expressed when a fertilised human egg is no more than a ball of cells but at the same time stem cells form which generate the human body. Now the question is whether it follows the ethic values of our society.
