Abstract: BACKGROUND: Angiogenesis is a key component of bone reconstruction. Promoting bone vascularization thereby can accelerate bone repair. There are numerous research methods for promoting angiogenesis, and significant progress has been made in the field of bone defect repair in recent years.  
OBJECTIVE: To review several cutting-edge methods and developments in promoting angiogenesis and repairing bone defects in recent years, as well as their applications in bone tissue engineering.
METHODS: The first author used the Chinese search terms “angiogenesis, osteogenesis, bone defect, tissue engineering, exosomes” and English search terms “angiogenesis, osteogenesis, bone defect, exosomes, vascularization” to find relevant publications in CNKI, WanFang, PubMed, and Web of Science databases. After screening and excluding articles irrelevant to the research purpose and repetitive articles, 69 articles were finally selected for review.  
RESULTS AND CONCLUSION: At present, promising results have been achieved in the bone defect remodeling research. Bone vascularization can be promoted by growth factors, delivery genes, biologically active ions, small molecule active peptides, and Chinese medicine monomers. Each has its own advantages and challenges, and faces different challenges. The synthesis of small molecule active peptides has low cost, high efficiency and safety, with obvious advantages. It has the potential to generate new ideas and methods for vascularization in bone tissue engineering.
