Technical Data
Vimentin (FLJ36605, VIM)
Vimentin (57kD) is the intermediate filament protein (IFP) of mesenchymal cells. It is the only IFP, which deviates from the tissue-specific and developmentally regulated pattern of expression. Besides its typical expression in most cultured cells, vimentin is also expressed together with several other IFPs during early stages of development. As differentiation proceeds, vimentin is exchanged for the tissue-specific intermediate filament type.
Desmin (53kD) exhibits a high degree of tissue specificity, its expression being predominantly confined to all types of muscle cells (cardiac, skeletal and smooth muscle). Regulation of desmin expression is stage and tissue-specific, since it is induced during terminal development. In skeletal en cardiac muscle cells desmin is localized in the Z-disk region and at the intercalated disk. The expression pattern of desmin in smooth muscle is much more heterogenous.
Coexpression of vimentin and desmin has been observed in rhabdomyosarcomas and leiomyosarcomas.
