So with more research on how to maintain temperatures of these extremophiles, investigatores will find more uses for them, such as flavoring of foods, improve the uptake of medicines by the body, and reduce bitterness and mask unpleasant ordors in foods and medicines. Researchers already learned how to produce sheep and other animals by genetically copying cells isolated from early-stage embryos. She attracted a lot of press because she drew attention to the theoretical possibility of cloning humans. Cloning is based on nuclear transfer which involves the use of 2 cells. Researchers also found that the ability to produce offspring from cultured cells open easy ways to make transgenic animals which are important for research and can produce medically valuable human proteins.
Stem cells help repair or replace tissue damaged by illness.
What I believe to be most interesting is the fact that researchers can differentiate stem cells so that it may be possible to manufacture cells to repair or replace damaged tissue that illnesses has caused such as AIDS, Parkinson s, muscular dystrophy, and diabetes. To get stem cells to match an individual person, they create an embryo by nuclear transfer, which is 2 cells, and they use one of the persons cells as the donor and a human egg as the recipient. The embryo is then allowed to develop only to the stage needed to separate and culture stem cells from it. But that s my belief. Scientists are trying to figure how to make cloning easier and they re also trying to save humans.
