In preimplantation embryos, stage-specific embryonic antigen (SSEA)-1, SSEA-3, and SSEA-4 are well-known carbohydrate marker antigens that show a stage-specific expression. SSEA-1 is usually carried by glycoproteins and/or glycolipids, while SSEA-3 and SSEA-4 are mostly carried by glycosphingolipids, which are the major constituents of raft microdomains. Biochemical analysis and confocal laser-scanning microscopic study of raft microdomains have been conducted in cultured cell lines. Here, we show the dynamic movement of SSEA-4 in the raft microdomains of preimplantation mouse embryos by immunostaining with 6E2, a novel anti-SSEA-4 monoclonal antibody, and subsequently discuss the role of raft microdomains in early embryogenesis.
