Abstract:

BACKGROUND: Bone morphogenetic protein 9 has been proven to be the strongest osteogenic growth factor in the bone morphogenetic protein family.
OBJECTIVE: To explore the research progress of bone morphogenetic protein 9 induced osteogenic mechanism and its application.
METHODS: Web of Science, PubMed, WanFang and CNKI were searched using “bone morphogenetic protein9/BMP9, bone ingrowth, bone tissue engineering, osteogenic differentiation, cytokines” as key words for relevant articles published from 1989 to 2019. A comprehensive analysis and review was performed after removal of irrelevant and repetitive literature.
RESULTS AND CONCLUSION: To date, bone morphogenetic protein 9 has been shown to be one of the most potent growth factors for inducing the osteogenic differentiation of mesenchymal stem cells in vitro and in vivo in the 14 bone morphogenetic protein family members. Moreover, bone morphogenetic protein 9 plays an important role in the repair of bone and cartilage damage and in promoting osteogenic differentiation. Bone morphogenetic protein 9 is also known as growth differentiation factor 2, and its mechanism underlying osteogenic induction is very complicated. Its signaling pathway involves various osteogenic signaling pathways, and various growth regulators are also involved in the entire osteogenic induction by bone morphogenetic protein 9. The osteogenic mechanism of bone morphogenetic protein 9 is different from the osteogenesis mechanism of other bone morphogenetic protein family members. In animal experiments, bone morphogenetic protein 9 can promote fracture healing, cartilage formation, and spinal fusion. Therefore, bone morphogenetic protein 9 has a great potential in basic research.

Key words: bone morphogenetic protein 9, osteogenic induction, bone regeneration, bone ingrowth, osteogenic differentiation, mesenchymal stem cells
