Dental pulp stem cells (DPSCs) are multipotent stem cells with the potential to differentiate into various cell types. For this reason, they have been proposed as an alternative source for mesenchymal stem cells. Somatostatin is a peptide hormone with an inhibitory effect on several endogenous hormones. The aim of our study is to investigate whether somatostatin can promote or inhibit differentiation of DPSCs in osteoblasts and bone tissue. DPSCs were extracted from third molars of healthy subjects, and were treated with somatostatin at the concentration of 100 ng/ml for 24 and 48 h. Gene expression in treated DPSCs was compared with untreated cells (control) in order to check the effect of somatostatin on stem cell differentiation. After 24 h of treatment many genes investigated were down-regulated in treated DPSCs vs untreated DPSCs. Significantly up-regulated gene (Fold change > 2) was the Bone Morphogenetic Protein BMP4. On the contrary somatostatin induced the over-expression of bone related genes after 48 h of treatment (i.e. BMPR1B and BMPR2). TGFB family genes and their receptors were also significantly up-regulated after 48 h of treatment. Somatostatin demonstrated to promote the self-renewal of DPSCs: in our experiments somatostatin mainly acted on TGFB family genes. Further studies are needed to explore this new way of creating bone tissue.
