Cell Survival and Morphology in Response to Asp and NNDAsp Treatment. (A) Representative cell morphology indicated by inverted microscopy reveals cell viability of both Caco-2 cells and NCM-460 cells that were pretreated with 250 µg/ml of Asp and NNDAsp for 24 hrs. (B) The number of survived cells upon treatment with indicated compositions. Error bars indicate the standard deviation (S.D.) of three independent experiments. The student's two tails t-test was used to determine the significance of differentiated values. (*) indicates P-values ≤0.05, and (**) indicates the P ≤0.01.
