Abstract:

BACKGROUND: Bone regeneration and repair for bone defects is a common problem in the clinic. Bone regeneration requires specific microenvironment and growth factors. Nel-like molecular 1 (Nell-1) is a secreted protein, and it is also an effective bone growth factor without toxic effect. Nell-1 has been shown to promote bone regeneration and repair, and it is expected to be a new method for bone regeneration and repair.

OBJECTIVE: To review the mechanism of Nell-1 in osteogenesis and its application and prospects in bone regeneration and repair.
METHODS: PubMed, CNKI, WanFang and Embase databases were searched for the literature addressing Nell-1 in osteogenesis, bone regeneration and repair published between December 15, 1996 and November 1, 2017. The keywords were “nell-1, nel-like molecule 1, nel-like protein 1, neural EGF like protein 1, bone repairing, osteogenesis, osteogenic, regenerative medicine” in English and Chinese, respectively. The repetitive studies were excluded.
RESULTS AND CONCLUSION: Nell-1 was firstly found to be associated with craniosynostosis and later has been proved to be an effective bone growth factor. Nell-1 possesses the roles of anti-adipose differentiation, inhibiting inflammatory reaction without obvious toxic effects. A large number of animal experiments have proven that Nell-1 can be used to promote bone regeneration and repair. Additionally, it is also expected to be a potential drug for osteoporosis, and is a promising method in bone regeneration and repair.
