Abstract
In this editorial we comment on the review by Wang et al published in the recent issue of the World Journal of Gastroenterology in 2023. Small extracellular vesicles (exosomes) play important roles in the tumor microenvironment. In this review, the authors introduce the following points: (1) The composition and function of exosomal microRNAs (miRNAs) of different cell origins in hepatocellular carcinoma (HCC); (2) the crosstalk between exosomal miRNAs from stromal cells and immune cells in the tumor microenvironment and the progression of HCC; and (3) the potential applicability of exosomal miRNAs derived from mesen-chymal stem cells in the treatment of HCC. In addition, the potential applicability of exosomal miRNAs derived from mesenchymal stem cells in the treatment of HCC was introduced. In this review, the authors give us an overview of the exosomal RNA and summarize the function of exosomal RNA in HCC, which provides a deeper understanding of exosomal miRNAs to the readers.
