摘要:


文题释义:

促红细胞生成素:是一种由胎儿肝脏和成年人肾脏产生的调节红细胞生成的生长因子,对骨缺损后的血管生成和成骨作用有很大贡献。
骨组织工程:是指将分离的自体高浓度成骨细胞、骨髓基质干细胞或软骨细胞,经体外培养扩增后种植于一种天然或人工合成的、具有良好生物相容性、可被人体逐步降解吸收的细胞支架或称细胞外基质上,然后将这种细胞杂化材料植入骨缺损部位,从而达到修复骨组织缺损的目的。


背景:骨缺损是由许多因素引起的,如炎症、肿瘤、创伤或骨骼疾病等,促红细胞生成素通过作用于间充质干细胞,促进其向成骨细胞、破骨细胞分化,作用于血管内皮细胞诱导血管生成,促进骨缺损、软骨缺损的修复,是一种在骨组织工程构建中具有应用潜力的生长因子。

目的:阐述促红细胞生成素在骨组织工程中的应用及其潜在机制。
方法:由第一作者运用计算机检索中国知网、万方、维普数据库及PubMed数据库中2004-2022年发表的相关文献,以“Erythropoietin,Bone defect,Bone regeneration,Angiogenesis,Osteogenesis、Osteoblast,Osteoclast,Bone tissue engineering”为英文检索词,以“促红细胞生成素,骨缺损,骨再生,血管生成,成骨分化,成骨细胞,破骨细胞,骨组织工程”为中文检索词检索,并进行筛选、归纳与总结,最终纳入64篇相关文献进行综述。

结果与结论:①促红细胞生成素可以直接作用于骨髓微环境中的成骨细胞及破骨细胞,通过促进间充质干细胞向成骨细胞、破骨细胞、脂肪细胞、神经细胞和基质细胞分化,通过激活Wnt/β-catenin、缺氧诱导因子1α/血管内皮生长因子、p38MAPK和EphrinB2/EphB4等信号通路介导间充质干细胞完成成骨向分化;②通过调节红细胞的生成以改变血液的携氧能力,通过刺激血管内皮细胞促进血管生成,新生的血管可以将成骨所需的氧气、养分、生长因子和骨祖细胞携带到成骨的位置,从而促进骨形成和骨折愈合;③促红细胞生成素目前作为一种具有成骨成血管作用的生长因子,通过多种载药手段已被应用于壳聚糖、聚己内酯、生物陶瓷和纳米纤维等各类型支架材料研究中,并与其他生长因子如骨形态发生蛋白2,9等共同作用于支架材料表面参与了骨缺损的修复,在新型组织工程骨的构建中展现了其优异的实用性,具有潜在的临床应用价值。

Abstract: BACKGROUND: Bone defects are caused by many factors, such as inflammation, tumor, trauma or bone diseases. Erythropoietin can promote the differentiation of mesenchymal stem cells into osteoblasts and osteoclasts and act on vascular endothelial cells to induce angiogenesis and accelerate the repair of bone and cartilage defects. Erythropoietin is a growth factor with potential application in bone tissue engineering construction.
OBJECTIVE: To expound the application and potential mechanism of erythropoietin in bone tissue engineering.
METHODS: The first author searched the related articles published in CNKI, WanFang, VIP, and PubMed databases from 2004 to 2022 by computer. Search terms were “erythropoietin, bone defect, bone regeneration, angiogenesis, osteogenesis, osteoblast, osteoclast, bone tissue engineering” in Chinese and English. Finally, 64 articles were included for review. 
RESULTS AND CONCLUSION: (1) Erythropoietin can directly act on osteoblasts and osteoclasts in the bone marrow microenvironment by promoting the differentiation of mesenchymal stem cells into osteoblasts, osteoclasts, adipocytes, nerve cells and stromal cells. The activation of Wnt/β-catenin, hypoxia-inducible factor 1α/vascular endothelial growth factor, p38 MAPK and EphrinB2/EphB4 signaling pathways mediates the osteogenic differentiation of mesenchymal stem cells. (2) Erythropoietin can not only regulate the production of erythrocytes to alter the oxygen-carrying capacity of blood but also stimulate vascular endothelial cells to promote angiogenesis. The new blood vessels can carry oxygen, nutrients, growth factors, and bone progenitor cells necessary for osteogenesis to the osteogenic site, thereby promoting bone formation and fracture healing. (3) Currently, erythropoietin is being used as a growth factor with osteogenic and angiogenic effects in various types of scaffold materials such as chitosan, polycaprolactone, bioceramics, and nanofibers through various drug delivery methods. Erythropoietin, along with other growth factors such as bone morphogenetic protein-2 and bone morphogenetic protein-9, has been applied to the surface of scaffold materials to participate in the repair of bone defects. Erythropoietin has demonstrated excellent practicality in the construction of new tissue-engineered bone and has potential clinical application value.
