The study was projected to determine immunohistochemically vimentin positive cells by using anti-vimentin primary antibody, to eludicate ultrastructurally the morphological properties of these cells and, to examined the presence of villous M cells in villi epithelia. 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 exibited 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

Çalışma, Ankara tavşanı ileum epitelinde vimentin pozitif hücreleri anti-vimentin primer antikoru yardımıyla immunohistokimyasal olarak belirlemek, ince yapı düzeyinde bu hücrelerin sahip oldukları morfolojik özellikleri ortaya koymak ve villus epitellerinde FAE dışı villöz M hücrelerinin varlığını araştırmak amacıyla planlanmıştır. Çalışmada materyal olarak, on adet sağlıklı, erişkin Ankara tavşanı kullanıldı. İleumun Peyer plakları içeren ve içermeyen bölgeleri incelendi. İleal Peyer plaklarında dom bölgelerinin yüzeylerini örten folikülle ilişkili epitellerdeki (FAE) olgun ve olgunlaşmamış M hücreleri ile villus intestinalis epitellerindeki kupa hücreleri vimentin pozitif immunreaksiyon gösterdi. Elektron mikroskobik incelemede, olgun M hücrelerinin bazolateral bir invaginasyonla intraepiteliyal lenfositleri (İEL) çevrelediği görüldü. Olgunlaşmamış M hücreleri ve kupa hücrelerinin ise böyle bir paketlenme olmaksızın bir veya iki adet İEL’le yakın ilişki içerisinde olduğu belirlendi. Villöz M hücreleri ise ileal villus epitellerinde tespit edilemedi. Sonuç olarak, kupa hücrelerinin bir intraepiteliyal paketlenme olmaksızın İEL’lerle yakın ilişki içerisinde olması ve sitoplazmasında vimentin pozitif immunreaktivite göstermeleri nedeniyle olgunlaşmamış M hücrelerine benzedikleri, ancak ince yapı özellikleri değerlendirildiğinde bu hücrelerin villöz M hücreleri veya enterosit olmadıkları anlaşıldı
