Abstract:

BACKGROUND: As a cell secretory product in every tissue and organ, the extracellular matrix, by virtue of its unique biological properties, has become a unique regenerative biomaterial in clinical applications. As one of the important active substances in the extracellular matrix, glycosaminoglycan has remarkable biological characteristics.
OBJECTIVE: To review the research progress of the detection methods of glycosaminoglycan in extracellular matrix at home and abroad and compare these methods to provide reference information to optimize the methods of detecting glycosaminoglycan in the extracellular matrix.
METHODS: A total of 2 037 publications were retrieved by searching CNKI database using search terms “glycosaminoglycan”, “extracellular matrix” and by searching PubMed using search terms “determination methods of glycosaminoglycan” “Animal-derived extracellular matrix”. Sixty-three literatures were screened and included in the final analysis. The common methods of detecting glycosaminoglycan were summarized. According to the ideas summarized during the literature review, the improved method for glycosaminoglycan extraction and detection was proposed and a comparative study was designed to validate the improved method.  
RESULTS AND CONCLUSION: Glycosaminoglycan plays a vital role in the biological properties of animal-derived extracellular matrix and can confer superior biological activity and prosthetic function to extracellular matrix materials and products. Detection of glycosaminoglycan content in the extracellular matrix material can help to optimize extracellular matrix material. Therefore, the method of detecting glycosaminoglycan content in the extracellular matrix is of great importance. The currently available methods of detecting glycosaminoglycan include high performance liquid chromatography, uronic acid analysis, quantitative analysis of acetaminophen, and dimethyl methylene blue detection. All of these methods have certain limitations. Based on the existing research results, we only improved the sample digestion and glycosaminoglycan extraction in dimethylmethylene blue detection method, which greatly increased the accuracy of the detection results. This provides ideas and insights for other glycosaminoglycan detection methods.
