Engineered mesenchymal stem cell-derived extracellular vesicles as programmable biomaterial platforms for liver fibrosis: design principles, manufacturing and clinical translation
Liver fibrosis remains a major unmet clinical challenge characterized by persistent activation of hepatic stellate cells (HSCs), chronic inflammatory remodeling, and impaired hepatocyte regeneration. Although mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) have emerged as promising cell-free therapeutics...
