It would be very prudent to test your cultures (good and bad) for
mycoplasma. The method of fluorescent staining of 3T3 cell cultures
inoculated with some of the medium from your neuronal cultures, using a
DNA stain like Hoechst or DAPI, would be the simplest to carry out.
Further, is it possible to passage the evil influence (or putative
agent) to some other cultures that seem normal and transfer the
cytopathology you have observed?
