Interesting question. My answer is no, but it requires a rather science-fiction style answer - at least it's beyond current technology, but here goes: My Assumptions I make the simplifying assumption that aging is only related to telomere length. Thus by "avoid aging" I assume you mean "avoid telomere shortening" (more precisely prevent telomeres reaching ...
Many studies, including those of Hayflick himself, have found a strong correlation between a species' Hayflick limit and its maximum lifespan. For example, Galapagos tortoises, which can live over a century, have a Hayflick limit of 90-125, and mice, which live only a few years, have a Hayflick limit of 14-28. However, the mechanism connecting the maximum ...
First of all, in eukaryotes (as far as I'm aware), older cells can be distinguished from younger cells due to telomere shortening, so there is an ageing process. HeLa cells mentioned by @Gary Chou have a more active telomerase which mitigates telomere shortening, allowing cells to continue to divide indefinitely. I think it's a very interesting question ...
In term of eukaryotic cells, most of them are mortal and will indeed age (the famous telomere sequence for example). However due to mutation some cells do achieve immortality such as HeLa cell line widely used in bio research.
