Mesothelioma Cells
Mesothelioma is a rare but highly aggressive malignancy arising from the mesothelial lining of the pleura, peritoneum, or pericardium. Strongly associated with asbestos exposure, these tumors are characterized by a long latency period and significant resistance to conventional chemotherapy and radiation.
Our mesothelioma cell line collection provides specialized in vitro models representing various histological subtypes, including epithelioid, sarcomatoid, and biphasic mesothelioma. These cell lines are indispensable for investigating the molecular mechanisms of mesothelial transformation, identifying early diagnostic biomarkers, and developing novel therapeutic approaches such as immunotherapy and targeted gene therapy.

FAQ
How do I choose between epithelioid and sarcomatoid mesothelioma cell lines?
Epithelioid lines are the most common and generally grow as more organized cobblestone-like monolayers. Sarcomatoid lines represent a more aggressive subtype, showing spindle-like morphology and increased resistance to standard therapies. Biphasic models exhibit characteristics of both.
What is the significance of BAP1 mutation in these cell lines?
BAP1 is one of the most frequently mutated genes in mesothelioma. Cell lines with BAP1 deficiency are critical for studying epigenetic dysregulation and identifying vulnerabilities that can be targeted by PARP inhibitors or other DNA-repair-focused therapies.
Can mesothelioma cell lines be used to study asbestos-related oncogenesis?
Yes, these lines are widely used to study the long-term cellular responses to mineral fibers and how chronic inflammation leads to the malignant transformation of mesothelial cells.
Are these cell lines suitable for testing Mesothelin-targeted therapies?
Absolutely. Many mesothelioma cell lines overexpress Mesothelin, making them ideal targets for testing CAR-T cell therapies, antibody-drug conjugates (ADCs), and other immunotherapies.
What are the recommended culture conditions for mesothelioma cells?
Most mesothelioma lines thrive in RPMI-1640 or DMEM supplemented with 10% FBS. However, some lines may require specific growth factors. We provide detailed culture protocols for each specific cell line to ensure optimal growth.
