Some members of the bone morphogenetic protein subfamily (BMP-2 and -7) are currently used in orthopedic surgery for several applications. Although their use is considered safe at short term, the high doses of growth factors needed make these treatments expensive and their safety uncertain at long term. BMP-6 has been much less studied than BMP-2 and -7, but some authors suggest that this BMP might have a stronger osteogenic activity than the previously mentioned. Having in mind that angiogenesis plays a well-known role during bone formation, the aim of this work was to study the effect of combining BMP-6 with bFGF on both the growth and differentiation of MC3T3-E1 mouse preosteoblasts and rat bone marrow-derived mesenchymal stem cells (MSCs), as well as on in vivo osteogenesis. We demonstrate that a low dose of bFGF enhances the osteogenic differentiation of MSCs induced by BMP-6 in vitro. Furthermore, we also demonstrate that bone formation in vivo induced by BMP-6 can be accelerated and enhanced by adding a low dose of bFGF, what might suggest a synergic effect between these growth factors on in vivo osteogenesis.
