Figure 3. Occludin immunocytochemistry (ICC, A and B) and transepithelial electrical resistance (TEER, C).

Figure 3

A) Immunocytochemistry of Caco-2/HT29-MTX monolayers maintained in MEM media (mineral deficient) and supplemented with 58Fe. B) ICC of control cells maintained in MEM media supplemented with65Zn isotope. The addition of Zn improves the definition of the tight junction protein occludin. C) Transepithelial resistance (TEER) of cells treated with 9.7 × 10−6 mg/mL zinc oxide nanoparticles in DMEM or in digest for 4 hours. Bars that do not share any letters are significantly different according to a one-way ANOVA with Tukey’s post test (p < 0.05).
