I do not know your set-up, but maybe it is possible to grow the cells in
Bromdesoxyuridin, than do the staining with the commercially available
anti-BrDU antibodiy. This technique is usually done to determine the
number of dividing cells in a population. You can easily find literature
on this in medline, I should think.
