abstract

  • Giant cell tumor of bone in a neoplastic stromal cell which survives for multiple passages in primary cell culture with a stable phenotype. In the pathological environment of GCT, the neoplastic nature of the mesenchymal stromal component drives local hematopoietic precursors to undergo fusion and form multinucleated osteoclast like giant cells. There is currently very limited knowledge about the pathogenesis of GCT due to the lack of suitable in vivo models for this tumor. Here we report stable gene transfer of Green fluorescence protein (GFP) in GCT stromal cells. In the present study, we have used GCT stromal cells that stably express enhanced green fluorescence protein (GFP) that are used in a new in vivo culture model. Our results show the utility of the GFP tagged cell lines that stably express GFP signals up to 52 weeks of continuous growth. The in vivo model described herein can serve as an excellent system for in vivo therapeutic and mechanistic evaluation of existing and novel targets for GCT.
