Effects of repeated treatment with TiO2 NMs on the viability of differentiated Caco-2 and HepaRG cells. Caco-2 cells (A, B) and HepaRG cells (C, D) were treated with concentrations of NM-103 (A, C) and NM-104 (B, D) ranging from 5 to 80 ug/cm2 for 24 h (light blue circles), 24 h with a 1-week recovery period (dark blue squares), 1 week (light orange triangles), 1 week with a 1-week recovery period (orange inverted triangles) or 2 weeks (black diamonds). Data are presented as the mean ± SEM from three independent experiments
