MSC-Derived Extracellular Vesicle-Delivered L-PGDS Inhibit Gastric Cancer Progression by Suppressing Cancer Cell Stemness and STAT3 Phosphorylation

Figure 3

EVs-L-PGDS increased L-PGDS and reduced stem cell marker expression and inhibited STAT3 phosphorylation in the gastric cancer cell SGC-7901. (a) Confocal microscopy for the location of EVs in SGC-7901 cells (×600). (b) Western blot for the expression level of L-PGDS in SGC-7901 cells. (c) Quantitative analyses of protein expression of L-PGDS. (d) Western blot for the expression level of Oct4, Nanog, and Sox2 in SGC-7901 cells. (e) Quantitative analyses of protein expression of Oct4, Nanog, and Sox2. (f) Western blot for the expression of p-STAT3 (Thy705), t-STAT3, and GAPDH in SGC-7901 cells. (g) Quantitative analyses of protein expression of p-STAT3 (Thy705). ; , , and .
