Do any cells last a lifetime?

Aron Stack  asked the Naked Scientists:

   

Hi Chris,



I had a question I was hoping you could help with.



I know that over the course of our lives we lose lots of cells that die and are replaced, but I wondered what cells are with us (if any) from birth until death? Presuming one lives to be 60 or so plus.



Thanks



Aron



What do you think?

Most of your neurons, and many of the eye cells last a lifetime.  That is one of the reasons why people have problems with the lenses of the eyes changing over time.

Most of the bone actually gets remodelled over time.

Another one is the ova in human women- in a woman's lifetime, she creates a certain amount of egg cells, but they are never replaced. Once they're gone, they're gone.
