Lectin histochemistry of metastasizing and non-metastasizing breast and colon cancer cells.

Glycosylation of the tumour cell surface is of importance in metastasis formation as indicated by lectin-binding studies. In particular, binding of the lectin HPA is associated with metastasis formation, both in clinical studies and in xenograft models of breast and colon cancer. Here we examined if there is an association between the HPA-positive glycotopes of metastasizing cancer cells and selectin-binding properties.
