Effect of curcumin on the growth of human multiple myeloma cells.

Curcumin inhibits the growth of human multiple myeloma cells. U266 (panel A), RPMI 8226 cells (panel B), MM.1 (panel C), or MM.1R (panel D) (5000 cells per 0.1 mL) were incubated at 37°C with curcumin (1 μM and 10 μM) for the indicated time, and the viable cells were counted by means of the standard trypan blue dye-exclusion test. The results are shown as the means (± SDs) cell count from triplicate cultures.
