Uses by pathologists. Vimentin staining confirms mesenchymal origin of some tumors; may be the only positive stain and thus confirms that the tissue is capable of staining ( Am J Surg Pathol 2011;35:1722 ) Staining may confirm mesenchymal origin, but numerous exceptions so relatively nonspecific.

Vimentin is a good candidate but it can stain other types of cells too. I think that you need to try a few of the options suggested above especially Seppe's idea with FSP-1. Cite

For full image see PMID 28665955. Flow Cytometry - Anti-Vimentin antibody [EPR3776] - Cytoskeleton Marker (ab92547) Myofibroblasts usually stain for the intermediate filament vimentin which is a general mesenchymal marker and "alpha smooth muscle actin" (human gene = ACTA2) and for palladin, which is a cytoskeletal actin scaffold protein. Mesenchymal and endothelial cells usually stain vimentin positive and thus act as a measure of internal quality control in immunoreactivity. Absence of immunostaining in these areas often indicates that there is significant damage to tissue antigens and loss of structural architecture. We retrospectively reviewed the pathology archives in our institution for all specimens with vimentin stain between 2000 and 2016. The cases were classified into epithelial, hematolymphoid, melanocytic, mesenchymal, and unclassified groups, and the staining results were categorized as positive, negative, or unknown, based on the pathology report. CD99, a marker for MIC-2, reacts with normal Sertoli cells and granulosa cells.

Antibodies and image courtesy EnCor Biotechnology Inc. Vimentin is a type III intermediate filament protein that is expressed in Vimentin stains virtually all spindle cell neoplasms—mesenchymal spindle cell neoplasms and sarcomatoid carcinomas included. However, vimentin stains a subset of carcinomas regularly and to a significant degree, and this may be useful in the context of a panel of antibodies to narrow a differential diagnosis. Three alcohol-fixed lung cancers and two blocks of alcohol-fixed pleura failed to stain for vimentin. By contrast, all mesotheliomas and carcinomas, whether alcohol or formalin fixed, as well as sections of pleura, were strongly positive when stained with anticytokeratin antibody 35 beta H11. Vimentin Staining in Mouse 3T3 Fiboplasts Fluorescence staining techniques are frequently used in biological and medical research for diagnosis due to their high specificity and sensitivity.

Vimentin staining in a lymphoma. Vimentin is a common immunostain. It marks most soft tissue lesions and malignant melanoma. It is usually negative in carcinomas. Vimentin Antibody Staining Protocol for Immunohistochemistry . Description: This monoclonal antibody reacts with the intermediate filament protein vimentin present in cells of mesenchymal origin.

Cervical cancer is one of the commonest types of cancers worldwide especially in developing countries. Intermediate filaments protein family has shown a role in the diagnosis of various cancers, but a few studies are available about the vimentin and cytokeratin roles in the cervical cancer.

Stains were performed on consecutive slides. For each stain, the figures shown are from tissue samples Vimentin is present in nasal and lung epithelial cells, and it may also be present in the extracellular space of the lungs and other tissues.
