  • Title: Lectins as markers of rumen epithelial cell differentiation.
    Author: Neogrády S, Gálfi P, Veresegyházy T, Bardócz S, Pusztai A.
    Journal: Histochem J; 1994 Mar; 26(3):197-206. PubMed ID: 8206789.
    Abstract:
    Lectins of different carbohydrate specificities (GNA (Galanthus nivalis), con A (Canavalia ensiformis), VFL (Vicia faba), PSL (Pisum sativum), LCA (Lens culinaris), PNA (Arachis hypogaea; with or without prior neuraminidase treatment), WGA (Triticum vulgare), SBA (Glycine max), UEA-I (Ulex europaeus), LPA (Limulus polyphemus), BS-I B4 (Bandeiraea simplicifolia, isolectin B4)) were explored for use as differentiation markers of rumen epithelial cells in vivo and in vitro. Lectins specific for mannose (GNA), mannose/glucose (con A, VFL, PSL and LCA), N-acetylglucosamine (WGA) or for N-acetylneuraminic acid (LPA) reacted generally with all types of rumen epithelial cell from both rumen tissue and cell culture. They were, therefore, not suitable markers of epithelial differentiation. SBA was unsuitable because, although it reacted with both tissue and cultured rumen epithelial cells, it was also bound to non-stratified areas of primary rumen epithelial cell cultures. Both BS-I B4 and PNA (after neuraminidase treatment) had to be ruled out because they did not react with differentiated rumen tissue epithelial cells, although they did bind to both stratified and non-stratified cultured cells. In contrast, UEA-I reacted strongly with differentiated rumen epithelial cells both from rumen tissue and cell cultures and therefore appears to be a good general marker for rumen epithelial cell differentiation.
