Immune cells raised after PM2.5 exposure during pregnancy. (A) PM2.5 increased Leukocyte number, addition of GMI decreased the level. (B) The percentage of immune cells. (D–F) Number of different inflammatory cells increased in response to PM2.5 exposure. GMI could decrease the inflammation of PM2.5. *, and ** indicate p < 0.05, and p < 0.01 significant difference, respectively, compared with control. #, and ## show p < 0.05, and p < 0.01, respectively, compared with PM2.5-treated controls.
