Don't kill embryos can be successfully extracted stem cells

Technology channels () message: no damage to the original embryo, scientists from human embryos on acquisition of a single cell, has been successfully developing human embryonic stem cells, and can make it into the body of any other types of cells. To date, the stem cell cultivation requires from a mature embryos in a large number of collected cells, so that the embryo inevitably affected by the injury.

This new technology will allow researchers to manufacturing for treatment and in-depth study of human embryonic stem cells, and to effectively avoid the traditional methods for the destruction of human embryos of fierce controversy. In addition, scientists can also use this method to collect cells, used for IVF in regular checks to see if there are genes in the embryo. Moreover, such a check process does not harm the embryo of further development.

United States biotechnology group advanced cell technology Inc (Advanced Cell Technology) Research Department Vice President Robert Lanza biologists said the company has led the human embryonic stem cells into the many have the effect of cell types. These cells including vascular cells, heart attack can be used to repair the heart; there are eyes cell, you can save people's eyesight.

In permitting, Pallanza and his colleagues on 16 do IVF laboratory of no use embryos experiments. They use tiny diyanyao from early embryo collection in a single cell, then each embryo is only 8-10 cells.

Use the collection of cells, scientists develop a second major performance and stability of human embryonic stem cell lineage. They can be continuous replication for a few months, and then develop into other types of cells. However, you have to have more research to determine these new embryonic stem cell is and other human embryonic stem cells.

It may be helpful in the area attract more public funds, and to increase the attractiveness of the business investment. Lanza said the company will work with an IVF clinical departments work together to complete the procedures in this way biopsy can be used for preimplantation genetic diagnosis, can also be used for stem cells generate.

Dartmouth College (Dartmouth College) ethics Institute Director, advanced cell technology company independent Ethics Committee responsible Ronald • green (Ronald Green) indicates that this discovery "is expected to progress in regenerative medicine has played a key role".

"It appears to address the United States and other countries the political stalemate in a way," Professor green added, "I recognize it as the Bush Administration's a real opportunity, the Government can meet people on embryonic stem cell line requirements, while maintaining its moral position, that is, when you get the embryo should not damage it. ”

However, these experiments have in other species can be reproduced on to indicate that this discovery is right, "this is a solid job of a good example," Whittier Institute for diabetes-sea of Albert, says this important papers illustrates the use this method of stem cells and other human embryonic stem cells the difference and similarities.
