Bone Morphogenetic Protein 9 Enhances Osteogenic and Angiogenic Responses of Human Amniotic Mesenchymal Stem Cells Cocultured with Umbilical Vein Endothelial Cells through the PI3K/AKT/M-TOR Signaling Pathway

The authors investigated the effects of bone morphogenetic protein 9 on osteogenesis and angiogenesis of human amniotic mesenchymal stem cells (hAMSCs) cocultured with human umbilical vein endothelial cells (HUVECs) and determined the possible underlying molecular mechanism.
