Have we found the key to eternal youth? Scientists successfully turn back the clock in old human cells

 Stanford University has found a way to increase the length of telomeres

  • These are the protective caps on chromosomes that keep DNA healthy
  • To make the discovery, researchers used modified messenger RNA
  • This caused cells to behave as if they are younger and multiply quickly
  • It could also provide hope for battling the illnesses such as diabetes

Eternal youth could be one step closer following the successful transformation of old human cells into young ones.

The process increases the length of the ‘telomeres’, which are the protective caps on the end of chromosomes that impact ageing and disease.

Researchers in the US say the technique could extend human life and provide new hope for battling diseases that arise from old age.

Telomeres – often described as being like the plastic caps on the end of shoelaces – help keep DNA healthy.

These protective end caps become shorter with each DNA replication, and eventually are no longer able to protect DNA from sustaining damage and mutations, causing people to age.

WHAT ARE TELOMERES?

Telomeres are the protective caps on the ends of the strands of DNA called chromosomes, which house our genomes.

In young humans, telomeres are about 8,000-10,000 nucleotides long.

They shorten with each cell division, however, and when they reach a critical length the cell stops dividing or dies.

This internal ‘clock’ makes it difficult to keep most cells growing in a laboratory for more than a few cell doublings. Read full article…
