GFP Reporter Cell Line - mBMSC

Mouse Bone Marrow-derived Mesenchymal Stem Cells (mBMSCs) are highly characterized multipotent stromal cells isolated from the bone marrow compartment of mice. Growing as plastic-adherent, spindle-shaped fibroblasts, they are foundational in stem cell biology due to their robust self-renewal capacity and proven tri-lineage differentiation potential into osteoblasts, chondrocytes, and adipocytes. The GFP Reporter Cell Line - mBMSC enhances this critical mammalian model through the stable genetic integration of the Green Fluorescent Protein (GFP) gene. This precise engineering allows the cells to constitutively express GFP, providing a bright, distinct, and highly stable fluorescent signal that can be readily detected using standard optical equipment. Crucially, the genetic modification process is carefully executed to preserve the fundamental biological integrity of the primary cells. The engineered mBMSCs strictly maintain their native multipotency, proliferative dynamics, and characteristic immunophenotype—typically remaining positive for stromal markers like Sca-1, CD29, and CD90 while being negative for hematopoietic markers like CD45 and CD34—ensuring researchers have a biologically authentic and traceable model.

The constitutive expression of the GFP reporter transforms the mBMSC cell line into an invaluable tool for complex in vitro assays and targeted preclinical animal modeling within regenerative medicine and immunology. In standard laboratory environments, the robust green fluorescence allows researchers to continuously monitor cellular morphology, viability, and population dynamics during long-term differentiation protocols using live-cell fluorescence microscopy. The distinct signal also provides an optimal platform for advanced co-culture experiments and precise single-cell sorting via flow cytometry, enabling scientists to visually and quantitatively distinguish the stem cells from surrounding host tissue cells. In preclinical in vivo research, these GFP-labeled cells are widely utilized in localized transplantation models to study fracture healing, ischemic injury repair, and tumor tropism. The stable GFP marker facilitates precise post-mortem histological tracking and high-resolution intravital imaging.
