Hybrid type glycolipids (lacto-ganglio series) with a novel branched structure. Their presence in undifferentiated murine leukemia cells and their dependence on differentiation
Authors:R Kannagi  S B Levery  S Hakomori
Abstract:The structures of these glycolipids are hybrids of the lacto and ganglio series, which are characterized by the presence of GlcNAc beta 1----3 and GalNAc beta 1----4 linked to the Gal residue of Gal beta 1----4Glc beta 1----1Cer. This new hybrid series can be designated as "lacto-ganglio series." These glycolipids are present in undifferentiated murine leukemia cells. Their concentration declines with differentiation and they are virtually absent in differentiated M1+ cells, suggesting that lacto-ganglio structures could be markers of undifferentiated, malignant myeloid cells.
