Unexpected discovery about stem cell immortality study

“An exciting outcome of this research is that it definitively shows the critical protective element at chromosome ends is the telomere DNA loop,” said Associate Professor Cesare.
“This likely explains why telomere length regulates ageing; cells must need long enough telomeres to make the DNA loops and this becomes difficult as cells age.”
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.
