This was a key finding, as telomeres serve important functions in cell division and protecting mammalian chromosomes.

In an associated press release author Dr Mark Iles summarised the research, «Telomeres have been described as being like the plastic tips on shoelaces that protect the shoelace from fraying, just as telomeres protect chromosomes from degrading or fusing to one another.

Linkage on cp26 of a gene such as ospC, which is needed only during a brief phase of the infectious cycle, with a gene encoding a presumably essential housekeeping function, such as telomere resolution, assures retention of a critical trait during extended periods in which it confers no selective advantage.

When Szostak heard about Blackburn's Tetrahymena repeat sequences, he proposed testing whether they would function as telomeres in his yeast system.

First a chromosome is catastrophically shattered when it loses the caps on its ends, known as telomeres, that hold it together.

Izpisua Belmonte added that more extensive studies will be needed to fully understand the role of heterochromatin disorganization in aging, including how it interacts with other cellular processes implicated in aging, such as shortening of the end of chromosomes, known as telomeres.

Of course, these stem cells would eventually peter out too, as their telomeres were worn down — but this is just the same situation that we face with all aging damage.

Researchers also determined that these mutations cause excessive shortening of the ends of chromosomes, known as telomeres.
