Cd138 Cells Multiple Myeloma

However decreased expression of cd138 is frequently observed in plasma cells of myeloma patients although the clinical significance of this is unclear.

Cd138 cells multiple myeloma.

The purified cd138 cells are well suited for further flow cytometry functional or molecular analysis. Macsprep multiple myeloma cd138 microbeads have been developed for the positive selection of cd138 cells directly from anticoagulated whole blood or bone marrow by using the automacs pro separator or manual separators without additional density gradient centrifugation nor erythrocyte. Multiple myeloma is the 2nd most common blood cancer in adults with a median survival time of 5 years despite high dose chemotherapy and bone marrow transplantation interventions. However as a result of treatment with bortezomib one of the most widely used therapeutic agents cd138 might be negative or underexpressed which makes this marker unsuitable for detection of residual plasma cells.

Mm is a genetically complex highly heterogeneous malignancy with significant inter and intra patient clonal variability. To evaluate the significance of low expression of cd138 in mm we exami. Cd138 expression is a hallmark of plasma cells and multiple myeloma cells.

Syndecan 1 or cd138 is a heparan sulfate coated glycoprotein which is highly expressed on the surface of plasma cells and myeloma cells important for adhesion and. Multiple myeloma mm is a plasma cell malignancy and the second most common hematological neoplasm in adults comprising 1 8 of all cancers. Stromal reactivity was noted in 7 multiple myeloma cases. Multiple myeloma is a form of cancer caused by b cell neoplasia that results in dysregulated production and clonal expansion of malignant plasma cells cells that express cd138 syndecan 1 and are involved in the production of antibodies during an immune response.
