Ruthenium red binding to cell coat in neoplastic neurogenic cell lines in culture.

The cell coat of cultivated fetal rat brain cells as well as malignant rat neurogenic cell lines in culture were studied by transmission electron microscopy with the ruthenium red staining technique. Some of the transformed cell lines demonstrated alteration in the bindng properties of ruthenium red to the cell surface. Otherwise no significant correlation between the visualized cell coat thickness and neoplastic transformation was noted.
