Majority of the CSMSCs contained mannose, glucose, poly-saccharides with N-acetylglucosamine and N-acetylgalactosamine molecules, and lacked fucose, based upon the specific lectin screening. These carbohydrate molecules could determine the extracellular matrix and/or cell-cell binding and immunological properties of the cells (Data shown are mean ± SEM, N = 8; for abbreviations see Fig. 1).
