Effect of CeO2 NP on SA-β-gal activity in HSFs. (A) HSFs were irradiated by serial doses of UVA (50, 100, or 200 mJ/cm2) and stained with SA-β-gal. Scale bar = 50 μm. (B) Representative fluorescence images of cell nuclei stained with DAPI (blue) and SA-β-gal (green) in cells pretreated or not with CeO2 NP before exposure (or not) to UVA radiation (100 mJ/cm2). Scale bar = 20 μm.
