Carcinoid showing the expression of vimentin (VIM) in mesenchymal cells in the tumor stroma and in normal surrounding soft tissue.
Vimentin (VIM) - Marker for mesenchymal cells
Vimentin is an intermediate filament protein ubiquitously expressed mesenchymal cells, and is therefore used clinically to identify mesenchyme and sarcoma tumors. The function of vimentin is to provide cellular integrity and cell shape by supporting and anchoring organelles within the cytoplasm.
