In the current study, we found that α7 integrin-positive human skeletal muscle stem cells (α7<sup>+</sup>hSMSCs) could differentiate into the odontoblast lineage under specific inductive conditions in response to bone morphogenetic protein-4 (BMP-4). Cell aggregates of FACS-harvested α7<sup>+</sup>hSMSCs were treated in suspension with retinoic acid followed by culture on a gelatin scaffold in the presence of BMP-4. Following this protocol, α7<sup>+</sup>hSMSCs were induced to down-regulate myogenic genes (<italic>MYOD</italic> and α7 integrin) and up-regulate odontogenic markers including dentin sialophosphoprotein, matrix metalloproteinase-20 (enamelysin), dentin sialoprotein, and alkaline phosphatase but not osteoblastic genes (osteopontin and osteocalcin). Following retinoic acid and gelatin scaffold/BMP-4 treatment, there was a coordinated switch in the integrin expression profile that paralleled odontoblastic differentiation where α1β1 integrin was strongly up-regulated with the attenuation of muscle-specific α7β1 integrin expression. Interestingly, using siRNA knockdown strategies revealed that the differentiation-related expression of the α1 integrin receptor positively regulates the expression of the odontoblastic markers dentin sialophosphoprotein and matrix metalloproteinase-20. These results strongly suggest that the differentiation of α7<sup>+</sup>hSMSCs along the odontogenic lineage is dependent on the concurrent expression of α1 integrin.</p></abstract><kwd-group><kwd>Bone Morphogenetic Protein (BMP)</kwd><kwd>Cell Adhesion</kwd><kwd>Cell Motility</kwd><kwd>Integrins</kwd><kwd>Stem Cells</kwd><kwd>Muscle</kwd><kwd>BMP-4</kwd><kwd>Odontoblast</kwd><kwd>Retinoic Acid</kwd></kwd-group><funding-group><award-group><funding-source id="CS100">National Institutes of Health</funding-source><award-id rid="CS100">R01DE015404</award-id></award-group></funding-group></article-meta></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
