Abstract

Background: Titanium dioxide (TiO2) is employed in the production of cosmetics, sunscreen, food, and drugs; however, TiO2 is toxic at the nanometric scale. Objective: To analyze the in vitro toxic effect of TiO2 NPs on mesenchymal stem cells (hMSCs). Methods: The hMSCs from Wharton`s jelly were exposed to 4, 62.5 and 500 μg/mL of TiO2 NPs. Viability and cell proliferation tests were carried out at 2, 5 and 7 days of exposure. Additionally, the osteogenic and adipogenic differentiation capacity was evaluated. Results: TiO2 NPs had a perinuclear arrangement and internalized in vesicles into cytosol, diminished significantly the viability (40% and 30% and 30%) and the proliferation cellular (35%, 50% and 55%), differentiation to osteoblast (38%) and adipoblasts (20%). Conclusion: TiO2 NPs affect viability, proliferation, and differentiation of hMSCs. Our result suggests more regulation of the use of TiO2.
