Representative work: Hepatocellular carcinoma (HCC) is one of the dominating causes of cancer-related death throughout the world. Treatment options for patients with HCC vary, however, the lack of effective targeted drugs is the major reason for death in advanced HCC patients. In this study, a delivery system based on mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) loaded with doxorubicin (Dox) was developed. In this system, we initially erased terminal linked α2-3 and α2-6 sialic acids on the surface of EVs by neuraminidase. The exhibition of galactose (Gal) and N-acetylgalactosamine (GalNAc) residues in treated MSC-EVs can specifically be recognized by asialoglycoprotein receptor (ASGPR) of he Hepatocellular carcinoma (HCC) is a prevalent primary liver cancer often associated with chronic hepatitis B virus infection (CHB) and liver cirrhosis (LC), underscoring the critical need for biomarker discovery to improve patient outcomes. Emerging as a promising avenue for biomarker development, proteomic technology leveraging liquid biopsy from small extracellular vesicles (sEV) offers new insights. Here, we evaluated various methods for sEV isolation and identified polysaccharide chitosan (CS) as an optimal approach. Subsequently, we employed optimized CS-based magnetic beads (Mag-CS) for sEV separation from serum samples of healthy controls, CHB, LC, and HBV-HCC patients. Leveraging dat
