I'm growing some NIH3T3 cells, and recently I have always seen some
particles floating around or stick on the plate. The size is similar
the cells. The shape of my cells are also varied. Some look like
with a lot of streching outs. some have very large nuclear. Is that
that I got some contaminations, what could that be? since my cells are
still growing, I don't think it is yeast. But the appearance of my
NIH3T3 really makes me worried. Could it be mycroplasma?
thank you a lot.
