Adult cells turned into stem cells in the body

Conclusion This study is the first to induce stem cells within the body of an adult mouse, without the need to take the cells out of the body. The way that the researchers achieved this required the use of genetically engineered mice whose cells all had the genetic capacity to “reprogramme” into stem cells when treated with a specific drug. When these mice were given the drug, some of their cells “reprogrammed”, and some of these went on to form tumours. The technique used in this study is clearly not something that can be directly applied to humans – who cannot be genetically engineered in the way laboratory mice can be. Researchers did not have the ability to stop the reprogrammed cells from forming tumours within the mice’s bodies, or to “direct” the cells to repair specific tissues or develop into specific organs. Doubtlessly this study will prompt further research into seeing if this is possible. Although the study is an advance, it seems like the approach is better suited to helping scientists to understand stem cell biology through animal experiments rather than forming the basis of potential new treatments. Greater understanding of stem cell biology is in itself useful in helping researchers to develop stem cell-based treatments.   Analysis by Bazian. Edited by NHS Choices.
