LP-1 Cells

Model to study the process of B lymphocyte maturation.

The LP-1 cell line is a well-established human multiple myeloma cell line derived from a patient with multiple myeloma. It is characterized by its t(4; 14)(p16; q32) translocation, which results in the dysregulated expression of fibroblast growth factor receptor 3 (FGFR3). This genetic aberration is a hallmark of a subset of multiple myeloma cases and is associated with the pathogenesis and progression of the disease. LP-1 cells express a functional FGFR3, which, when activated, can engage the MAP kinase signaling pathway, promoting cell proliferation and survival. Notably, LP-1 carries a non-activating F384L mutation in the FGFR3 gene, distinguishing it from other myeloma cell lines with activating mutations of FGFR3.

LP-1 cells are useful for studying the role of FGFR3 in multiple myeloma, particularly in the context of non-activating mutations. Research has shown that in multiple myeloma, FGFR3 mutations and other common oncogenic mutations, such as those in the Ras family, are typically mutually exclusive, suggesting that these mutations may contribute to tumorigenesis through similar or overlapping pathways. This makes LP-1 an invaluable model for exploring the molecular mechanisms underlying multiple myeloma and for testing targeted therapies aimed at the FGFR3 pathway.

In addition to its relevance in FGFR3-related studies, LP-1 is also significant in research focused on the broader aspects of myeloma biology, including the role of cytokines like interleukin-6 (IL-6) in cell survival and proliferation. This cell line has been instrumental in studies that investigate the interactions between myeloma cells and their bone marrow microenvironment, as well as in the development of novel therapeutic strategies aimed at disrupting these interactions to control disease progression.

Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods.
To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections.
