Background: CD15/Lewis X
Lewis X (Lex)
is a glycan structure (Gal beta 1-4(Fuc alpha 1-3)GlcNAc beta -) that forms the terminus of N-linked
carbohydrates such as the antigenic epitope Stage-Specific Embryonic Antigen-1
(SSEA-1/CD15). It is widely expressed, can be found on glycoproteins,
glycolipids and proteoglycans and is a blood group antigen. Lex is a
marker for mouse embryonic stem and cancer cells, and is expressed on
leukocytes, germ cells and neuronal stem cells in both mouse and human. Lex
is thought to enhance cell adhesion, either directly or by promoting integrin
