MedSci点评:这是刚刚发现的新的骨形成相关信号Sema4D/Plexin-B1,与以往骨形成相关信号,如UPP-SMADs, Eph/ephrin,BMP6-SMADs,OPG/RANKL/RANK系统,Wnt/β2-catenin,DKK/LRP5/6信号等,这一新的信号发现,将有助于人们对骨质疏松,骨吸收以及骨形成的理解,同样,也会产生大量相关文章。希望看到本文的作者，可以依此信号，或将这

MedSci点评:这是刚刚发现的新的骨形成相关信号Sema4D/Plexin-B1,与以往骨形成相关信号,如UPP-SMADs, Eph/ephrin,BMP6-SMADs,OPG/RANKL/RANK系统,Wnt/β2-catenin,DKK/LRP5/6信号等,这一新的信号发现,将有助于人们对骨质疏松,骨吸收以及骨形成的理解,同样,也会产生大量相关文章。希望看到本文的作者，可以依此信号，或将这一新发现的信号与以往研究的信号相互作用进行研究，很容易发现一些新的有价值的线索。当然，还可以从临床病例入手进行研究。如果需要相关协助，可以与MedSci联系。 日本研究人员日前发现一种遏制骨骼形成的蛋白质，通过抑制这种蛋白质的功能，研究人员成功地在实验鼠身上实现了骨骼再生。 东京医科齿科大学研究人员报告说，他们在实验中发现，分解骨质的破骨细胞会大量分泌一种与调节免疫机能有关的蛋白质“Sema4D”，这种蛋白质会遏制成骨细胞的产生，进而阻止新骨骼的形成。 研究人员制作出能够与“Sema4D”蛋白质结合从而遏制其发挥作用的抗体，然后注射到患有骨质疏松症的实验鼠体内，结果发现其骨骼成功再生，骨密度也
