EFFECT OF SERUM ON HUMAN BONE MARROW STROMAL CELLS: EX VIVO EXPANSION AND IN VIVO BONE FORMATION

Our data demonstrate that for ex vivo expansion of human BMSCs, medium with FBS remains most effective. However, incubation of human BMSCs in SFM prior to in vivo transplantation significantly stimulates subsequent bone formation. This finding increases the practicality of using culture-expanded BMSCs for autologous human transplantation and suggests the presence of osteogenic inhibitors in serum.
