Reinforced Epithelial Barrier Integrity via Matriptase Induction with Sphingosine-1-Phosphate Did Not Result in Disturbances in Physiological Redox Status

Figure 3

Fluorescence intensities of supernatants of control and S1P (200 ng/mL)- and suramin (50 μM)-treated groups determined with Amplex Red assay. At the start of the treatment IPEC-J2 cells were not completely differentiated. The measured values are indicated as average fluorescence intensities ± SEMs (). There were no significant differences between mock and matriptase activator-treated groups () up to 48 hr.
