MSTO-211H Cells

The MSTO-211H cell line is derived from a patient with biphasic mesothelioma, specifically from a pleural effusion. It is classified as metastatic, and the patient had not undergone prior radiation or chemotherapy treatments before the establishment of the cell line. MSTO-211H cells are notable for expressing several markers that are significant in understanding both their biological behavior and their potential utility in cancer research. These cells possess high-affinity binding sites for epidermal growth factor (EGF), a property that may contribute to their proliferative capabilities, as EGF is a key regulator of cell growth and differentiation. The presence of EGF receptors suggests these cells could be useful in studying pathways related to growth factor signaling in cancer. In addition to EGF receptors, MSTO-211H cells express neuron-specific enolase (NSE), an enzyme typically found in neurons and neuroendocrine cells. NSE expression in MSTO-211H cells may be indicative of a neuroendocrine differentiation potential, a feature that can be significant for understanding the heterogeneity of mesothelioma tumors. Furthermore, the cells express both the alpha and beta subunits of human chorionic gonadotropin (HCG), a hormone typically produced during pregnancy but also known to be secreted by certain cancers. The expression of HCG subunits in MSTO-211H cells suggests a possible role in tumor biology, potentially related to immune evasion or tumor progression mechanisms. These markers collectively highlight the complex nature of this cell line, making it a valuable model for investigating mesothelioma biology and the effects of therapeutic agents.
