Abstract

This study demonstrates that podocalyxin, a heavily glycosylated type 1 transmembrane protein, is a glycoprotein ligand of rBC2LCN on human induced pluripotent stem (iPS) cells and embryonic stem (ES) cells. When analyzed by DNA microarray, podocalyxin was found to be highly expressed in both iPS cells and ES cells. The carbohydrate antigens of rBC2LCN are expressed on O-glycans of podocalyxin, since alkaline hydrolysis greatly reduced the binding of rBC2LCN to human iPS cells and ES cells. rBC2LCN bound to an O-glycan carrying H type 3 epitope structure isolated from iPS cells, suggesting that H type 3 is a novel pluripotency glycan marker.
