L-929-GFP Cells

L-929-GFP cells are a fluorescently labeled derivative of the murine L-929 fibroblast cell line, which was originally established from subcutaneous connective tissue of an adult mouse. The parental L-929 line is one of the most extensively used mouse fibroblast models in biomedical research and is characterized by its adherent growth, spindle-shaped morphology, and robust proliferative capacity. L-929 cells are widely utilized in studies of cytotoxicity, inflammation, extracellular matrix biology, and host–pathogen interactions, and they are also commonly employed for the production and bioassay of cytokines such as tumor necrosis factor-α (TNF-α).

The stable expression of green fluorescent protein (GFP) in L-929-GFP cells enables direct visualization and quantitative tracking of fibroblast behavior in real time. These cells are particularly useful for fluorescence-based applications including migration assays, co-culture experiments, tissue engineering studies, and live-cell imaging. L-929-GFP cells retain the core biological characteristics of the parental fibroblast line while providing enhanced utility for monitoring cell localization, proliferation, and interactions within complex cellular environments. Consequently, they serve as a versatile model for investigating stromal cell dynamics, wound healing processes, biomaterial compatibility, and immune-mediated cytotoxic responses.

Genetic modification: Stably modified by replication-incompetent lentiviral transduction to express the ZsGreen1 green fluorescent protein reporter; maintained as a polyclonal population under puromycin selection (1–5 µg/mL). S1/BSL-1 containment.
