Abstract
In addition to adult bone marrow-derived mesenchymal stem cells, more recently, a second large stromal compartment found in adipose tissue has received attention and is believed to contain multipotent cells. In vitro, adipose tissue-derived stromal cells (ADS) can differentiate down osteogenic, chondrogenic, myogenic, adipose, and even neuronal pathways. In this article, we explore the effect of fibroblast growth factors 2 (FGF-2) on ADS cells. Our results demonstrated that FGF-2 inhibits osteogenesis in ADS cells. The osteogenic inhibitory effects is dose-dependent and reversible, thus suggesting that the lack of osteogenesis observed in ADS cells exposed to FGF-2 is not due to a negative selection triggered by this factor on a subpopulation of osteoblast progenitors. Furthermore, either overexpression of FGF-2, or continuous FGF-2 treatment sustain the proliferative and osteogenic potential state of ADS cells. Therefore, FGF-2 appears to be a positive regulator of osteoprogenitor cells and a negative regulator of osteoblast differentiation in ADS cells. These FGF-2 functional characteristics may assist with cell selection and enrichment for the purpose of bone tissue engineering.
