... that the poorly differentiated cells which appear in this membrane have features in common with visceral endodermal cells. Using plant lectins reacting with the rat visceral endoderm (DBA, PNA, SJA and BSA-1) it was demonstrated that the proliferating endodermal cells retrodifferentiate to earlier stages...

...Halina Sobis; Michel Vandeputte The expression of receptors for lectins reacting with extraembryonal endoderm was compared between mouse and rat at different stages of gestation. Fluorescein-conjugated Helix pomatia agglutinin (HPA), Dolichos biflorus agglutinin (DBA), Sophora japonica agglutinin...

... for molecular mass heterogeneity and lectin binding activity. From 10 to 50% of the released glycoconjugates were present as a heterogeneous array of glycoconjugates of molecular mass > 250 kilodaltons. The remaining glycoconjugates were dispersed in a molecular mass range extending down to ∼ 15 kilodaltons...

... of developmental malformations and for the differential diagnosis of some cancers. The results obtained using different methods are compared with special reference to lectin affinity electrophoresis and lectin affinity chromatography. In addition, a self-explanatory nomenclature of AFP variants is proposed...
