  • Description: Keratinocyte cell line representing a recurring acantholytic carcinoma that originating in the same site as the primary invasive and ultimately metastatic SCC tumour. Background and Research Application MET2 is derived from a recurrent epidermal tumour from the back of a left hand, which in time progressed through to an invasive and metastatic lesion. Histology of the original tumour showed an acantholytic squamous cell carcinoma. MET2 has been used to understand aggressive recurring SCCs which ultimately metastasise and is an important cell line for this specific stage in SCC cancer progression. MET2 is the second cell line in a unique series of epidermal cell lines representing different stages of malignant transformation were derived from a single adult immunosuppressed individual. Four keratinocyte lines (PM1-4) established from forehead skin are here compared with 4 squamous cell carcinoma (SCC) lines (MET1-4)(MET1, MET4) derived respectively from a primary cutaneous tumour, two local recurrences and a distant metastasis of invasive SCC. Despite altered growth properties, the PM lines retained many features of normal keratinocytes including keratin phenotype, differentiation capacity and non-tumorigenicity in athymic mice. In contrast, from early passage, the MET lines displayed markedly reduced growth requirements, abnormal differentiation, aberrant K18 expression and tumorigenicity in athymic mice. The abnormal keratin profile of individual MET lines closely reflected the keratin phenotype of the tumour of origin. Although unusual HPV types were identified in the original tissue, there was no evidence of the persistent virus within any cell line and it appears that HPV is not critical for maintenance of the immortal phenotype. The PM lines were distinctly different from invasive SCC lines and are likely to be useful in studies focusing on mutations that are important in early neoplastic progression. The SCC series represent primary, recurrent and metastatic carcinoma. Availability of such a series from the same individual will facilitate genetic analysis of the malignant process.
