Features and Benefits

The MOC (Mouse Oral Cancer) cell lines provide a syngeneic HNSCC cancer model that can be transplanted into C57BL/6 mice. These lines are important models for immune cell infiltration studies. The MOC lines have been utilized to compare and identify potential clinical scenarios that are applicable to human Oral Squamous Cell Carcinoma. The MOC22 cell line was derived from primary tumors in a C57BL/6 WT mouse and shows indolent growth compared with the aggressive, metastatic MOC2 line.

Target description

Despite ongoing efforts to understand growth and signaling pathways in head and neck squamous cell carcinoma (HNSCC), patient outcomes have remained largely unchanged in recent decades. A significant barrier to understanding and studying immune responses in the context of cancer in recent years has been the lack of available syngeneic mouse models. Xenograft approaches have historically been popular models, but they unfortunately do not model important adapative immunity responses.The MOC cell lines have expanded our understanding of CXCL14 downregulation in metastatic lymph nodes. Previously, CXCL14 expression had been associated with T-cell associated mechanisms for tumor suppression. Tumor Infiltrating Lymphocyte (TIL) studies using MOC1 and MOC2 have found a cell-specific association in Oral Squamous Cell Carcinomas (OSCCs) involving CXCL14 downregulation resulting in TIL increase which leads to tumor suppression.The MOC group of cell lines contained common HNSCC mutations in addition to human-related OSCC driver pathways. All MOC lines share RAS pathway mutations and MOC22 was found to have HRAS mutations which is relevant in relation to human HRAS-mutant OSCC groups.

Storage and Stability

MOC22 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 cell marker expression and functionality.
