摘要:

文题释义:
miRNA:是一类高度保守的组织特异性非小蛋白非编码RNA,具有通过识别同源序列以及抑制mRNA翻译或促进mRNA降解在转录后水平调节基因表达的能力。
骨髓间充质干细胞是来源于中胚层的多能干细胞,广泛存在于骨髓、脂肪、脐带等组织,在特定条件下,可以分化为成骨细胞、成软骨细胞、上皮细胞、心肌细胞和肝细胞等。

背景:研究发现,miRNA 与骨髓间充质干细胞自我更新、多向分化、命运决定、功能行使等有着密切的联系,已经成为医学领域的研究热点。
目的:文章综述miRNA对骨髓间充质干细胞的调控作用及其可能存在的分子机制。
方法:以“BMSCs,miRNA,proliferation,osteogenic differentiation,adipogenic differentiation,chondrogenic differentiation”为英文检索词,检索PubMed数据库中2011至2021年的相关文献。通过阅读文题和摘要进行初步筛选,排除与文章主题不相关的文献,最终纳入51篇文献进行结果分析。
结果与结论:miRNA通过靶向成骨、成脂、成软骨分化相关基因和信号通路发挥作用。大量miRNA已被证明与骨质疏松症、骨关节炎等骨代谢疾病相关,而这些疾病严重影响患者的生活质量,给社会造成重大负担,因此对miRNA进行更多深入的研究与探索,更好地理解这些miRNA的调控机制将有助于开发靶向治疗骨代谢相关疾病的方法。

Abstract: BACKGROUND: Studies have confirmed that miRNAs are involved in self-renewal, multidirectional differentiation, fate determination, functional exercise and other aspects of bone marrow mesenchymal stem cells, and have become a hot spot in the medical field. 
OBJECTIVE: To review regulatory effect of miRNAs on bone marrow mesenchymal stem cells and its possible molecular mechanism. 
METHODS: PubMed was retrieved with the key words of “BMSCs, miRNA, proliferation, osteogenic differentiation, adipogenic differentiation, chondrogenic differentiation” in English. The retrieval time was from 2011 to 2021. After initial screening of titles and abstracts, irrelevant articles were excluded, and 51 eligible articles were included for result analysis. 
RESULTS AND CONCLUSION: miRNA plays an important role by targeting major genes and signaling pathways related to osteogenic differentiation, adipogenic differentiation, and chondrogenic differentiation. A large number of miRNAs have been shown to be associated with bone metabolic diseases such as osteoporosis and osteoarthritis, which seriously affect the quality of life of patients and impose a heavy burden on society. Therefore, more in-depth research and exploration on miRNAs and a better understanding of the regulation of the expression of these miRNAs will contribute to the development of targeted therapies for bone metabolism related diseases.

Key words: stem cells, bone marrow mesenchymal stem cells, miRNA, proliferation, differentiation, review
