Physical, chemical and morphological changes of bread polyphenol extract on cellular cultures monolayer CaCo-2

The effect on potential transepithelial electrics resistance (TEER) and the electronic scansion microscopy analysis (SEM) of CaCo-2 cells line monolayer could be one useful method to study the different antioxidant or pro-oxidant capacity values of different concentrations of the hydrolizated polyphenol extracts of bread made with wheat Sant’Agata cultivar (HBPE).The various concentrations of HBPE have been tested on culture in monolayer CaCo-2 cells seeded on polycarbonate filter, in the cell culture chamber (Ø 6.5 μm; area 0.33cm2; pore Ø 0.4 μm), at a density of 1.5x105 cells per filter and placed in a multiwells Falcon; the filter divided the chamber in apical and basal compartments tha…
