Description
DMS 53 cell line is a small cell carcinoma of the lung (SCLC) isolated in 1974 from a mediastinal biopsy at time of diagnosis from a 54 year-old male patient prior to treatment. DMS 53 secrete a large variety of hormones including adrenocorticotropin (ACTH), bombesin (BN), calcitonin (CT), chorionic gonadotrophin (hCG), glucagon, growth hormone (GH), oxytocin-neurophysin (OT-NP), parathyroid hormone (PTH), somatostatin-like immunoreactivity (SRIF), thyroid releasing hormone (TRH) and 17beta-estradiol. Expression of cell surface antigens Leu-7, Class I HLA, CLASS II HLA and My23 (defined by AML-2-23 monoclonal antibody) has been shown. DMS 53 cells produce receptors for BN, epidermal growth factor (EGF), transforming growth factor-beta (TGF beta) and acetylcholine (AChR). This cell line was shown to be tumourigenic in nude, athymic mice.
Quality Control
DMS 53 Cell Line was tested and found to be free of mycoplasma, bacterial, viruses, and other toxins. All cells were above 95% viability before freezing.
