Unexpected discovery about stem cell immortality study – News – The University of Sydney
Independent groups of scientists investigating telomeres and stem cells have found what may lie behind their immortality – telomeres in pluripotent stem cells are…
Telomeres are the protective caps at chromosome ends. In adult cells, telomeres shorten each time a cell divides and this contributes to ageing and cancer. Pluripotent stem cells, however, are specialised cells that exist in the earliest days of development. These pluripotent cells do not age and have the ability to turn into any type of adult cell.
The surprise finding, published today in Nature, shows that telomeres in pluripotent stem cells are protected very differently than telomeres in adult…
