The table shows the number of vital cells after two hours of exposure to increasing concentrations of Vitamin C in the culture medium. The cell lines used in this experiment are variants of human myeloid leukemia cells, and include: HL60, NB4, K562, U937, NB4-R1, NB4/As). It is evident that the total number of cells in culture decreases by increasing the concentration of Vitamin C in the culture medium.
