the cell type specificity for these processes can be most readily explained by postulating that all cells can take up exogenous gangliosides but only melanoma and astrocytoma cells have sufficiently high levels of gm3 alpha 2 -- -- 8-sialyltransferase for the conversion of added neugc-gm3 to disialogangliosides to be effective .
