So, do you need to differentiate the parent cells from the ones resulted from
the division or proliferating?
May be is not your question.
What about staining with CFSE a bunch of cells and let them to divide and sort
the different peaks (usually 7, at least in normal cells such as T cells
proliferating) by FACS. The mean fluorescence as you know is going lower with
each division. Is that what you need?
Depending on the proliferation time you will be able to separate the last
progeny, as well as the intermediate.
In normal T cells after 5 days you can recover cells from each division. Not
sure if with a cell line you could do the same.

One solution is to insert a plasmid to serve as an internal barcode, but

Thanks Laura and sorry for the confusion.
What I am looking for is a way to tell cell line apart if they come from the
same parent. For human lines that are from different people, STR profiles are
perfect ... but for lines derived from the same original (parent) line ...
there is currently no easy way to tell the difference between parent line A and
children lines A1, A2 much less grandchild A1.3. Make sense ... If it was a
hybridoma, I would just sequence the CDRs.
A colleague of mine and I were thinking of inserting a "DNA barcode" in the
lines, probably via CRISPR so we can put in as innocuous a site as possible,
but before developing a solving I was really hoping one already existed ... so
I thought I would poll this group ...
All about cell line authentication ... one of the many building blocks needed
for RnR.

Thanks for the clarification! Obviously I was thinking in my type of
experiments, trying to identify new markers upon treatment with certain agents.
We used to have a Core here for identification of cell lines, but I am not sure
of it is still operating.
Thanks!
