Japanese researchers have said in a paper published online in the journal Nature Biotechnology that they have "imitation" embryonic stem cells by changing the culture of a gene linked to cancer, improving the safety of this stem cell technology in clinical applicationsPreviously, the study suggested that four genes must be implanted into skin cells in order to "replicate" embryonic stem cellsAmong them, "c-Myc" is a cancer-related gene, there are serious safety risksIn the latest study, a team led by Kyoto University professor Yukio Yamanaka implanted three other genes in addition to "c-Myc" into skin cells and changed the culture environment, as well as stem cells with embryonic stem cell functionThe new method takes about a week longer to grow stem cells than originally, but it's no less functionalHowever, Yamanaka said the safety risks of "imitation" embryonic stem cell technology have not been fully resolved because the new method still uses "retroviruses" to transport genes, and there are virus safety issues
