Cell therapies and stem cells

Telomere Biology and cell therapies

There is a strong relation between the success of cell therapies and telomere biology. First of all cell therapies are a tool of regenerative medicine that aim to treat those illnesses that are a consequence of aging, which is triggered by telomere attrition. Moreover, telomere length is an underlying key factor behind the success of these therapies.


Want to perform a study in cell therapies?

For each cell therapy treatment, millions of cells need to be administered1 , what mean that multiple doublings for a single cell would be required.


This extensive replication results in telomere shortening exhausting cells’ replicative potential2.

Clinical implications of the use of stem cells with short telomeres

Loss of:

  • homing capacity3
  • plasticity potential4,5
  • expression of trophic factors 6

As a consecuence:

  • Transplantation does not produce the desired effects or it could be harmful 5,7,8
