The incorporation of radioactively labelled fucose into the lipid fraction of cultured normal human cells and several human tumour-cell lines was examined as a function of the cell population density. Normal cells exhibited a density-dependent pattern of incorporation, whereas in tumour cells the radioactivity incorporated was independent of the cell population density. An exception was found among the tumour cells, which suggests a possible correlation between the loss of this marker and the ability to produce tumours.
