Stromal-derived Factor-1α signaling is involved in bone morphogenetic protein-2-induced odontogenic differentiation of stem cells from apical papilla via the Smad and Erk signaling pathways

Stromal-derived factor-1α (SDF-1α) is a chemokine signaling molecule that binds to the transmembrane receptor CXC chemokine receptor-4 (CXCR4) and carries out important functions in development tissue homeostasis. SDF-1α signaling via CXCR4 regulates the recruitment of stem and precursor cells to support tissue-specific repair or regeneration. In this study, we examined the contribution of SDF-1α signaling to the odontogenic differentiation of...
