Stem cells open a window on aging, cancer and a devastating disease

Stem cell research is in its infancy, but a new study led by Children’s Suneet Agarwal, MD, PhD, and George Q. Daley, MD, PhD, investigators in Children’s Stem Cell Transplantation Program, reveal these cells’ unique powers to teach us about devastating, hard-to-treat diseases – and, in this case, cancer and aging.
In Children with dyskeratosis congenita, a rare condition that leads to premature aging, genetic mutations impair a key enzyme called telomerase that builds up the tips of our chromosomes, known as telomeres. When cells aren’t able to maintain their telomeres, the chromosomes become vulnerable to all kinds of damage, and the cell “ages” more quickly and stops dividing. As a result, children with dyskeratosis congenita have bone marrow failure – they’re unable to make enough blood cells to sustain the body. This requires a bone marrow transplant – an especially punishing procedure for these children, whose other tissues and organs are also failing because of the disease. …
