Hypoxia-Inducible Factor 1α Induces Osteo/Odontoblast Differentiation of Human Dental Pulp Stem Cells via Wnt/β-Catenin Transcriptional Cofactor BCL9

The authors examined the role of B-cell CLL/lymphoma 9 (BCL9), which is downstream of hypoxia-inducible factor 1α and a Wnt/β-catenin transcriptional cofactor, in the osteo/odontoblastic differentiation of human dental pulp stem cells under hypoxic conditions.
