Objective To elucidate the effect of osteogenic growth peptide(OGP) on bone marrow stromal cells proliferation and differentiation in vitro. Methods Bone marrow stromal cells were cultured individually in medium contained various concentrations of OGP; and cell proliferation quantity
alkaline phosphatase activity and level of Cbfa1 mRNA were examined by means of MTT
enzyme-linked immunoreaction and reverse transfer polymerase chain reaction respectively. Results In vitro
the addition of OGP in cultures resulted in an increase of cell proliferation(P0.05)
ALP activity(P0.05) and level of mRNA for Cbfa1(P0.05). All concentrations (10
-11
- 10
-7
mol/L) of OGP were effective but the maximum response was obtained with 10
-8
mol/L OGP. Conclusion Our results demonstrate that OGP stimulates proliferation and sequential differentiation of bone marrow stromal cells in vitro.
