Schematic diagram of the treatment schedule for repeated exposure of differentiated Caco-2 and HepaRG cells with the two TiO2 NMs, NM-103 and NM-104. Blue arrows indicate exposure times, whereas green arrows indicate recovery periods in cell culture media without NMs. The various endpoints measured during each treatment condition are presented on the left
