LuM1 cells have been utilized for metastasis, migration, and invasion assays. LuM1 cells have been useful in understanding Matrix MetalloProteinase (MMP) protein expression and their relation to metastatic potential and tumor progression.

Tumor metastasis is one of the most life-threatening events in cancer and often leads to inevitable cancer growth that cannot be effectively treated. Treatment options after metastasis often involve slowing tumor growth or relieving harsh symptoms. The process of metastasis, known as the metastatic cascade, involves a series of events in which cancer cells break away from the primary tumor and begin growing in other tissues. This process proceeds by cancer cells moving through blood vessels or lymph nodes and spreading via the circulatory system to eventually colonize other more distant tissues. The importance of understanding metastasis remains continually relevant and requires a variety of models for understanding the underlying mechanisms. LuM1 (SCC654) and NM11 (SCC655) were developed together to provide two similar cell models with differing metastatic potentials. NM11 was selected as low-metastatic cell line and is derived from murine colon adenocarcinoma while LuM1 was developed through repeated tumor transplantation until metastatic potential of the cells had changed visibly through lung tumor nodule formation.
