In the well-known super.amily of tr.nsfor.ing gr.wth factor. beta (TGF-b), bone mor.hogenetic pr.teins (BMPs) ar. one of the most compelling cytokines for.their.major.r.le in r.gulation of cell gr.wth and differ.ntiation in both embr.onic and adult tissues. This subfamily was fir.t descr.bed for.its ability of potentiating bone for.ation, but nowadays, the power.of BMPs is well beyond the bone healing scope. Some of the BMPs have been well studied and descr.bed in the liter.tur., but the BMP9 is still wor.hy of attention. It has been shown by many author. that it is the most potent osteogenic BMP. Mor.over. it has been descr.bed as one of the r.r. cir.ulating BMPs. In this paper. we will r.view the r.cent liter.tur. on BMP9 and the differ.nt avenues for.futur. r.sear.h in that field. Our.pr.mar. scope is to r.view its r.lation to bone for.ation and to elabor.te on the available liter.tur. on other.systems.
