The invention describes specific sialylated structures present on human stem cells and cell populations derived thereof. The invention is especially directed to methods to control the status of stem cells by observing changes in sialylation of the cells; and control of potential contaminations of biological materials; and reagents and methods used in connection with the cells in order to avoid alterations of the cell glycosylation by contaminating materials. The invention is further directed to novel stem cells, the glycosylation of which has been specifically altered.

Method for evaluating cell populations

The invention describes methods for production of novel composition of glycans, glycomes, from human multipotent stem cells. The invention is further directed to methods for modifying the glycomes and analysis of the glycomes and the modified glycomes. Furthermore the invention is directed to stem cells carrying the modified glycomes on their surfaces.

Carbohydrate profile compositions from human cells and methods for analysis and modification thereof

The present invention reveals novel methods for producing novel carbohydrate compositions, glycomes, from animal tissues. The tissue substrate materials can be total tissue samples and fractionated tissue parts, or artificial models of tissues such as cultivated cell lines. The invention is further directed to the compositions and compositions produced by the methods according to the invention. The invention further represent methods for analysis of the glycomes, especially mass spectrometric methods.
