YUMMER1.G1A Mouse Melanoma Cell Line

As immune-based therapies in cancer models become more popular and applicable, a further need for immune-competent models has been presented. A wide variety of genetically engineered mouse models have been created to express vital melanoma genotypes. The variety in these models have allowed the study of genetic alterations that are relevant to human melanoma biology. While it is quite useful to have mouse models with genetically defined human melanoma characteristics, it is limited by complex mouse colony maintenance. The YUMMER1.G1A cell line was produced to be more experimentally relevant. The cell line was derived by backcrossing important alleles into C57BL/6J mice. The mice were interbred to produce human-relevant genetically defined mouse models that could then be used to generate cell lines. Melanomas were induced by applying 4-hydroxytamoxifen to induce Cre-lox allele recombination. Cells were then mechanically and enzymatically dissociated from the removed tumor. The melanoma lines generated from this procedure retained important human melanoma characteristics useful for studying disease progression.The YUMMER1.G1A cell line is derived from the YUMM1.G1 cell line (SCC230) which is sourced from a Mc1re/e female mouse model driven by Braf activation, Pten inactivation, and Cdkn2a inactivation.1 The YUMM1.G1 cells were further subcloned into the YUMMER1.G1A cell line by undergoing UVB radiation induced mutagenesis, resulting in high mutational burden. The cell line is positive for the common melanoma markers, MelanA and PMEL. The cells are syngeneic with C57BL/6J mice and are very tumorigenic in vivo.References:1. Meeth K et al.

YUMMER1.G1A 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.
