Figure 1From: Toxicity of CdSe Nanoparticles in Caco-2 Cell CulturesEffects of Cd2+ on (A) Caco-2 cell viability assessed with the MTT assay, and (B) Caco-2 cell attachment assessed via Hoescht cell nuclei staining. Data are expressed as the mean ± SE from three separate experiments using cells from different cultures. Statistically significant differences in relative viability between certain Cd2+ doses and control are indicated by an asterisk (*) (p < 0.05).Back to article page
