a LY1 cells. b LY8 cells. *The cell apoptosis at this IL-9 concentration was statistically significant compared to untreated cells (IL-9 concentration is 0). Cell apoptosis between groups at different IL-9 concentrations had statistical significance. This means that the apoptosis of LY1 and LY8 cells was dose-dependently reduced upon exposure to IL-9. IL-9 at a concentration of 80 ng/mL decreased cell apoptosis to approximately 70 % and 50 % of the baseline levels in LY1 and LY8 cells, respectively
