Hepatocellular carcinoma (HCC) seriously threatens human health and life quality. Natural killer (NK) cells play important roles in liver immune function. Bone marrow mesenchymal stem cell (BMSC) exosomes (Exo) participate in tissue damage. This study explored BMSC-Exo’s effect on NK cells’ anti-tumor activity. NK cells were isolated from the livers of mice with liver cancer. NK cells with or without BMSC-Exo treatment were co-cultured with liver cancer cells to assess cell proliferation. Administration of BMSC-Exo into mice with liver cancer significantly suppressed liver cancer cell growth. In addition, BMSC-Exo treatment significantly improved NK cells’ anti-tumor effect whic was related to BMSC-Exo-induced up-regulation of miR-1925. Implantation of BMSC-Exo into mice with liver cancer at different time periods can significantly suppress liver cancer cell growth. At the same time, BMSC-Exo implantation inhibited the expression of cell proliferation marker protein(Ki67). In vitro study found that BMSC-Exo treatment significantly increased miR-1925 level and the toxicity of NK cells to HCC cells. In addition, miR-1925 overexpression in NK cells significantly increased NK cells’ anti-tumor activity. In conclusion, this study proved that up-regulation of miR-1925 by BMSC can inhibit the growth of liver cancer by promoting the anti-tumor activity of NK cells.

Disseminated breast cancer cells have the capacity to metastasise to the bone marrow and reside in a dormant state within the mesenchymal stem cell niche. Research has focussed on paracrine signalling factors, such as soluble proteins, within the microenvironment. However, it is now clear extracellular vesicles secreted by resident mesenchymal stem cells into this microenvironment also play a key role in the initiation of dormancy. Dormancy encourages reduced cell proliferation and migration, while upregulating cell adhesion, thus retaining the cancer cells within the bone marrow microenvironment. Here, MCF7 breast cancer cells were treated with mesenchymal stem cell–derived extracellular vesicles, resulting in reduced migration in two-dimensional and three-dimensional culture, with reduced cell proliferation and enhanced adhesion, collectively supporting cancer cell dormancy.
