Research Abstract

In this study, we investigated the cross talk mechanism of intracellular signaling induced by multiple growth factors in periodontal stem cells. We found TGF-βwas crucial for commitment to pre-osteoblast lineage from periodontal ligament cells and ECM production in the presence of BMP2. DNA chip analysis revealed the Smurfs, Ski and Smad7, ubiquitin-proteasome system related genes, as the key determinants for cytodifferentiation to the calcified nodule forming cells.
