In this study, ten healthy, adult Angora rabbits were used as a material. It was examined the ileum with and without Peyer's patches. Immunohistochemical examination revealed the mature and immature M cells within FAE's and cup cells within epithelium of villi exibitcd the positive vimentin immunoreactivity. Electron microscopical examination revealed the mature M cells surrounded the intraepithelial lymphocytes (IEL) by a basolateral invagination. Whereas, immature M cells and cup cells were observed to be associated with one or two intraepithelial lymphocytes without such a pocketing. No villous M cells were found within epithelia of ileal villi. In conclusion, the cup cells are similar to immature M cells associated with IEL without a intraepithelial pocketing and showed a vimentin positive immunoreaction within their cytoplasms, but these cells are not villous M cells or enterocytes.trinfo:eu-repo/semantics/openAccessAngora rabbitcup cellsM cellsvimentinArticle57422923410.1501/Vetfak_00000024302-s2.0-77953877424Q3WOS:000283619400004Q4
