Kenneth,

We routinely do cell proliferation studies on rats and mice. I can't
answer your questions in detail at the moment as I am leaving on a
business trip later today.  If you can wait until Oct. 30th I can send
you the information that you would need.  

Answers to the following questions would help 
1- what organs are you interested in
2- are these archival tissues or have the animals yet to be treated
3- what were they fixed in and for how long (if known), or what are you
planning to fix them in
4- which part of the cell cycle are you wanting to look at

I am sure that the above information will allow me or someone else on
this list to help you.
