I work with cell cultures of an adherent cancer cell line and so do
some other scientists in our lab but they use a different cancer cell
line. Both cell lines have very different morphology so they can
easily be distinguished. Their cells are round and small, whereas my
cells are larger and stretched.
Now, as soon as my cell cultures have grown up a bit, I also tend to
see a lot of round and small cells, which - I first thought - are
cells that remained unadhered. I do not see these cells in the
beginning. However, comparing cell cultures from the other lab group
to these round and small cells in my cell cultures made me suppose
that this might be a cross-contamination with the other cell line.
Is there any way to confirm my assumption? Is there any way to get rid
of the cross-contamination?
