Abstract

Extensive studies have shown that undifferentiated cellular components of human bone marow are involved in the formation and renewal of bone tissue (osteogenic cascade). In this study, human mesenchymal stem cells were stimulated by bFGF, IGFI, PDGF-BB or TGF-ß1, in 2 different concentrations respectively (1 and 10 µg/mL). in vitro to assess their influence on differentiation to the osteoblastic phenotype. Thus human marrow could be used as a malleable basic element in bone engineering. The study clearly showed a stimulatory or suppressive effect of each of the respective growth factors. In particular the addition of TGF-ß1 directed the differentiation of mesenchymal stem cells of human bone marrow toward the osteoblastic phenotype.
