Pros of Human Cloning

If human cloning can be regulated appropriately, such as only allow to clone organs, the use of it will be beneficial to human being for medical purpose.

- Parents who have lost a child could have another baby

In 2002, a ten-year-old U.S. girl called Cady who was killed in a car crash. Her mother gave Dr Panos Zavos a blood sample taken from her daughter 26 hours after she died in order to fuse cow eggs with cells from corpses to create an animal-human hybrid. At the time, her mother said, "Cady was simply everything to me. If there is one chance in a billion that it would work, of course I want to do that. What I am doing is trying to give her biological presence in this world continuation." This is a mother expressing love for a daughter and trying to give her daughter life. 

-Medical breakthrough

We may learn how to switch cells on and off through cloning and thus be able to cure cancer. Scientists still do not know exactly how cells differentiate into specific kinds of tissue, nor they understand why cancerous cells lose their differentiation. Cloning, at long last, may be the key to understanding differentiation and cancer. 

We may be able to clone livers or kidneys for liver and kidneys transplants respectively.
Victims of terrible accidents that deform the face should now be able to have their features repaired with new, safer, technology.

- Good for infertile couples
With cloning, infertile couples could have children. Current infertility treatments are less than 10 percent successful. Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for many more infertile couples to have children than ever before possible.

Figure 1. Somatic cell nuclear transfer. Here, a skin cell is removed from a patient. The nucleus of this cell is placed inside an enucleated oocyte and stimulated to divide. The resulting blastocyst can either be used to make embryonic stem cells, which are genetically identical to the donor, or they can be brought to term to create a genetically identical human being.
