The role of bFGF on the ability of MSC to activate endogenous regenerative mechanisms in an ectopic bone formation model

The view depicting bone marrow (BM)-derived mesenchymal stem cells (MSC) as a uniform population differentiating into new-tissue builder cells is evolving toward the concept of a heterogeneous population of stem/progenitor cells secreting bioactive molecules, and contributing to establish an on-site regenerative microenvironment. We report that in an ectopic bone formation model the intrinsic MSC capability to activate endogenous regenerative...
