abstractText | FGF-2 stimulates bone formation in vitro and in vivo in rats. However, there are limited studies in mice and no data on the mechanism(s) by which FGF-2 induces bone formation. We assessed whether short-term FGF-2 treatment of marrow stromal cells from young mice would increase alkaline phosphatase-positive (ALP), mineralized colony formation and expression of genes important in osteoblast maturation. Short-term treatment with FGF-2 (0.01-1.0 nM) for the first 3 days of a 14- or 21-day culture period increased the number of ALP mineralized colonies in bone marrow stromal cells. FGF-2 (0.1 nM) increased the mRNAs for type 1 collagen: osteocalcin, runt domain/core binding factor, PTH/PTHR receptor, and insulin-like growth factor 1 (IGF-1) at 14 and 21 days. We conclude that short-term FGF-2 treatment enhances osteoblast maturation in vitro. Furthermore, the anabolic effect of FGF-2 may be attributed in part to regulation of IGF-1 in osteoblasts. |
