ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of vascular endothelial growth factor (VEGF) on bone marrow-derived mesenchymal stem cell (MSC) proliferation and explore the signaling mechanism involved.</p><p><b>METHODS</b>MSC culture was performed following the classical whole bone marrow adhering method. The characteristics of MSC were identified by induction of multi-lineage differentiation and flow cytometry for surface marker analysis (CD34, CD45, CD29, and CD90). Following the addition of 50 nmol/L wortmannin, 50 µmol/L PD98059, 30 µmol/L SB203580, 10 µmol/L H89, 20 µmol/L Y27632, 1 µmol/L rapamycin, 10 µmol/L straurosporine, 6 nmol/L Go6976, or 50 µmol/L Pseudo Z inhibitors in the cell culture, the MSC were treated with 20 ng/ml VEGF and the changes of the cell proliferation rate was measured with MTT assay.</p><p><b>RESULTS</b>Cultured MSC were capable of multi-linage differentiation and did not express VEGF-R, CD29 or CD90. Treatment with 20 ng/ml VEGF obviously promoted MSC proliferation, and this effect was inhibited partially by p38 mitogen-activated protein kinase (MAPK) inhibitor rapamycin, PD98059, SB203580, Go6976, and straurosporine.</p><p><b>CONCLUSIONS</b>VEGF promotes MSC proliferation in close relation to the AKT-PKC pathway, in which PKC signal pathway may play the central role.</p>
