ES cells are now having been thought to provide a way to treat diseases like Parkinson’s, juvenile diabetes, and Alzheimer’s by regenerating tissue.
And these technologies had a great improvement just in UK around these days.
The breakthrough, by US researchers, could assist the search for a cure for the common brain condition.
The embryonic "stem cells", reports the journal Nature Biotechnology, were grown into new tissue which was implanted into the mouse brain. Those embryonic stem cells - taken from a five-day-old embryo, are all the same, they have the ability, when placed in the right biochemical conditions, to be transformed into any cell type in the body.

The scientists are using the potential of stem cell that will create all types of cells to create part of the human body to cure cancer and birth disease.
(“Scientists believe that stem cells offer a realistic hope of treatments for Parkinson's disease.”)
(“Stem cells are the body's "master cells", and could be transformed into new brain cells to replace those lost to illness. “)
--Dr Lorenz Studer, Memorial Sloan-Kettering Cancer Center
It seems that every breakthrough of stem cell research is a break though of pharmacy.
All these development of the technology on stem cells are seemed to be the great improvement of human. But, it also brings the greatest problem of ethics.
After the stem cells are planted into the recipient’s body, the problem of rejection would come out, and the new cells would be dead. As a result, the recipient’s body would need to use powerful anti-rejection---- drugs.
The technique of stem cell using in medicine involves creating embryos and then destroying them after the stem cells have been harvested.
Ethicists believe that an embryonic cell is one complete life, which means that using embryonic cell in medicine is murdering.
Religious think that copying embryonic cell is considered to be an activation of clone. But clone against the faith.
“People shouldn't play God”
“It involves destroying embryos”
“Stem cell research is as same as clone research.”
“Opponents of the technique see this as an abortion”
—objections of cloning from the internet.
All the stem cell researches are continuing and there is not enough reason for people to stop them.
(All attempts to introduce a world-wide ban have been stymied because some countries want that to include the use of all cloning techniques in medical research.
However, many researchers believe the use of some cloning techniques could lead to a revolution in medicine. )

However, we are facing one question:
If faced with a degenerative or potentially fatal disease, should a person be able to refuse medical help because of his or her own moral principles if that help is available to them?
Well, we all know that if this research continues on. We’ll finally be able to cure cancer and birth disease—which are almost impossible to cure at the moment.
When people have kidney cancer, volunteers contribute kidneys to them. If the stem cell technique matures. Can you say that we can not use the embryonic stem cell because that the embryonic didn’t volunteer to contribute the cell, which means that we rather let the volunteer lost a kidney than a small cell?
“If you believe god creates human, you should also believe that god gives human the ability to study science, to change the environment, to change the world.”--- <<The 6th day>>
Remember, science is never evil. People can’t stop the improvement of technology. We should believe, although scientist brings the nucleus weapon while studying the nuclear technology, we are using electricity everyday from nuclear power station。
