Sulphated Polysaccharides and the Differentiation of the Cellular Slime Mould Dictyostelium Discoideum

SUMMARYCell surface and endocellular polysaccharides of growing and differentiated Dictyostelium discoideum have been isolated and characterized with electrophoretic and chromatographyc procedures.The mould exhibit a very eterogeneous family of sulphated polysaccharides which are externalized during the differentiation.The possible role of cell surface polysaccharides in the differentiation process is discussed
