Co-expression of vimentin and cytokeratins in M cells of rabbit intestinal lymphoid follicle-associated epithelium
Histochem J.
1992 Jan.
Abstract
Membranous epithelial (M) cells within the follicle-associated epithelium which overlies gut-associated lymphoid tissue in Peyer's patches and of appendix have been shown by immunocytochemical staining, in rabbit, to contain both vimentin- and cytokeratin-type intermediate filaments. The specificity of vimentin immunostaining has been confirmed by blocking with purified vimentin and by immunoblotting. No evidence was obtained for the expression of vimentin in rat, mouse or human M cells. The possible significance of vimentin-expression in these specialized epithelial cells and the potential use of vimentin as a positive marker for M cells are discussed.
