Figure 1

Effects 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).
