The effects of Cd on cell growth in ht-UtLM cells (A) and ht-UtSMCs (B) as measured by the MTS proliferation assay. Cd concentrations < 50 μM significantly increased cell growth in ht-UtSMCs, and at most low concentrations in UtLMs, whereas ≥ 50 μM Cd significantly inhibited cell growth at 24 hr, 48 hr, and 72 hr in both cell lines. Data were collected with an absorbance wavelength of 490 nm. Data represent mean ± SE of experiments repeated three times with independent cultures. ^ap < 0.05 compared with control at 24 hr. ^bp < 0.05 compared with control at 48 hr. ^cp < 0.05 compared with control at 72 hr.
