Can extract stem cells without damaging the embryo
Release date: 2006-10-31 According to Xinhua News Agency, London, October 26, the American scientists recently extracted cells from experimental mouse embryos without damaging the embryos and successfully cultivated stem cells.

According to the "Nature" magazine network on the 26th, researchers at Cornell University's Weill Medical School in the United States took more mature embryos from the experimental mice - a group of 20-25 cells called "inner cell population" The blastocyst, which is then softened with an enzyme that binds the "inner cell population", is then used to grow embryonic stem cells by implanting the embryos back into the test body before extracting one, two or three cells.
The researchers used three cell extracts to produce embryonic stem cells, but failed to grow with one or two cell extracts. Using this technique, the researchers used four blastocysts to produce four embryonic stem cell lines, which means a success rate of 25%.
The researchers believe that using this method to obtain embryonic stem cells, the embryos will not be damaged. This method is expected to be used in humans in the future. Women who have been fertilized by in vitro fertilization can use this technique to obtain embryonic stem cells, which can be used for research or for storage for the treatment of their children.
Obtaining a human embryonic stem cell line without destroying the embryo is a technique that has always been favored. Scientists are committed to cultivating embryonic stem cells because stem cell research can be applied to the treatment of various difficult conditions such as Alzheimer's disease, Parkinson's disease, and cirrhosis.
