Previous reports have shown specific binding characteristics of peanut lectin to a variety of lymphatic and epithelial tumors. This study demonstrates the presence of lectin binding sites on cell membrane of laryngeal cancer cells, but not on adjacent normal epithelial linings. It also demonstrates the presence of glycoconjugates responsible for lectin adherence in fetal larynges. The Thomsen-Friedenreich antigen is a glycoprotein structure participating in the structure of the MN blood group antigen. It is also the structure that binds the peanut agglutinin. Perhaps this antigen, which we found on fetal larynges as well as on malignant laryngeal epithelial lining, is another oncodevelopmental antigen.

The aim of the investigation was to decide whether changes in cell to cell adhesiveness took place during embryonic differentiation. The technique of Curtis (1969) was used to measure the adhesive behaviour of several types of ectodermal, neural and mesodermal cells of the chick embryo at stages 7 and 12 of differentiation. Cells dissected from segmented mesoderm were found to be more adhesive than cells from unsegmented mesoderm. Cells from the ectoderm were more adhesive than those from the neural tissue, at both stages 7 and 12. Cells from both ectoderm and neural tissue became more adhesive between stages 7 and 12. It is concluded that an increase in adhesiveness may play a role in somite segmentation, but not in neural tube formation.
