Effects of coumarins on keratinocyte growth with and without UVA light. PAM212 cells were grown in tissue culture dishes and treated with increasing concentrations of the coumarins. After 30 min at 37°C, cells were treated with (closed symbols) or without (open symbols) UVA light. Cells were then refed with fresh growth medium. After 4-5 days, cells were removed from the dishes and counted on a Coulter Counter. Data are presented as percent inhibition of cell growth relative to controls. Data represent means ± SEM (n = 3). In a typical experiment, control plates contained 5.5 × 104 cells.
