What is Somatic Cell Nuclear Transfer (SCNT) and Therapeutic Cloning for Stem Cells?

This process involves the nucleus of an egg cell, replacing it with the material from the nucleus of a "somatic cell" (a skin, heart, nerve or any other non-germ cell), and stimulating this cell to begin dividing. • This egg cell is never fertilized by sperm, and the genetic material within the cell is virtually identical to the genetic material extracted from the skin or other cell. • Once the cells begin dividing the stem cells can be extracted 5-6 days later.

• By using SCNT, scientists hope to understand how the protein factors in the egg cell cause these already specialized somatic cells to become stem cells. Once we learn how this cell "de-differentiation" occurs, we will no longer need to use egg cells. • Because of SCNT, science could advance to a point where millions of people will have access to life saving therapies developed using their own DNA.

• When cells, including donated organs, tissues, or blood, are transplanted or transfused, the recipient's body mounts a ...

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
