Cells treated with curcumin show mitotic as well as apoptotic morphological criteria depending on the applied curcumin concentration and co-treatment with light. Characteristic cell areas marked by yellow squares in Fig. 2 are herein shown in a higher magnification. Cells were treated for 1h with 0.6µg/ml (A, B) or 0.8µg/ml (C, D) curcumin. Cells that were kept light protected (A, C) showed clear mitotic activity after 16h whereas cells irradiated with VIS (B, D) showed membrane blebbing and complete cell retraction.
