Abstract:

BACKGROUND: Peripheral pulsed electromagnetic fields have an obvious effect on cartilage metabolism; however, its molecular mechanism is still unclear.
OBJECTIVE: To investigate the physical characteristics of pulsed electromagnetic fields and its mechanism and effect on cartilage formation.
METHODS: A computer-based online search of PubMed database, CNKI database, VIP database andWanfang database was performed to search related articles. “Pulsed electromagnetic fields, cartilage, cartilage cells, matrix, bone marrow mesenchymal stem cells” were used for word retrieval in the title, abstract, and keywords. Repetitive studies or old literatures were excluded.
RESULTS AND CONCLUSION: A total of 145 articles were retrieved in the initial search, and finally 46 articles were included in result analysis. The results showed that pulsed electromagnetic fields can promote the differentiation of bone marrow mesenchymal stem cells into chondrocytes and cartilage specific matrix such as type II collagen and proteoglycan synthesis, thus playing a cartilage inducing effect. Pulsed electromagnetic fields can also promote the expression of transforming growth factor beta 2 and other factors to regulate the chondrocyte growth and differentiation, which can realize the permanent repair of defects in clinic.

Key words: tissue construction, tissue construction review, pulsed electromagnetic fields, chondrocytes, cartilage matrix, cartilage induction, metabolism, bone marrow mesenchymal stem cells, type Ⅱ collagen, proteoglycan, transforming growth factor, review literature
