Description

General description

SCC625, the mEERL Lung Metastasis cell line (MLM), is one of the clones isolated from the lung metastasis of the inoculation of SCC627 mEERL cells that formed after the apparent disease clearance following a treatment by cisplatin and radiation. SCC625 was shown to be inherently more resistant to treatment than its parent. SCC625 showed ready tropism to the lungs upon re-injection into immunocompetent mice, plus a higher rate of metastasis and a greater number of metastatic tumors than its parent or the four other sibling clones isolated in parallel. While this clone has lost the luciferase expression of the parental SCC627, it retains the expression of many of the hallmark genes of OPSCC, including cytokeratin, E-cadherin, BRCA2, p16, and EGFR, and its spread has been tracked in vivo by such markers.

Application

MLM cells are verified to be of mouse origin and negative for human, rat, Chinese hamster, Golden Syrian hamster, and non-human primate interspecies contamination, as assessed by a Contamination Clear panel by Charles River Animal Diagnostic ServicesCells tested negative for infectious diseases against a Mouse Essential CLEAR panel by Charles River Animal Diagnostic Services.Cells tested negative for mycoplasma.

Features and Benefits

SCC625 MLM.3 Mouse Lung Metastasis Cell Line is a recurrent/metastatic model of HPV+ (human papilloma virus-positive) OPSCC cancers, and retains the heterogeneity and resistance characteristics of refractory human disease to serve as a translational system to test novel therapeutics.

Target description

Head and neck cancers represent the sixth most common cancers worldwide. Among them, incidence of oropharyngeal squamous cell carcinoma (OPSCC) are increasing, and a majority are caused by the human papilloma virus (HPV). While successful management methods exist, local recurrence and nodal metastasis result in mortality in a minority of cases. Historically, insights into HPV-induced transformation have been obtained in the context of cervical cancer and anogenital warts models. While much of this is relevant to OPSCC, systems in which the effects of HPV infection can be studied in the context specific to OPSCC are critical.​SOURCESCC625 cell line is a clone isolated from the lung metastasis of the mEERL cell line (SCC627) in a treatment-failed male C57BL/6 mouse. SCC627 is a luciferase-expressing derivative of the mEER cell line (SCC626). SCC626 was established by the retroviral transduction of the HPV16 E6 gene, HPV16 E7 gene, and the human hRas gene into the primary oropharyngeal epithelial cells isolated from a male C57BL/6 mouse.REFERENCES1.Kademani D. 2007.

Storage and Stability

MLM cells should be stored in liquid nitrogen until use. The cells can be cultured for at least 10 passages after initial thawing without significantly affecting the cell marker expression and functionality.
