Rice Cell Cocktail Tough on Cancer Cells, Nice to Normal Cells

(Science Daily) Juice from rice cells can knock out two kinds of human cancer cells as well or better than the potent anti-cancer drug Taxol, a Michigan Technological University scientist has discovered in laboratory tests. Plus, it does something Taxol can't do: it plays nice with normal cells.
Biologist Ramakrishna Wusirika and his team made their anti-cancer cocktail with blobs of rice stem-cells called calli, which they cultured in their lab using seeds of the garden-variety rice plant Oryza sativa. Then they collected secretions from these calli and applied them to colon and kidney cancer cells in the lab.
After 96 hours of exposure to a 20-to-1 rice callus solution, 95 percent of the kidney cancer cells were killed, along with 83 percent of the colon cancer cells, while normal lung cells were virtually unharmed. Taxol was lethal to the cancer cells too, but it also killed a significant number of normal cells.
Wusirika thinks the rice callus culture may be attacking cancer with the same sort of plant chemicals that make vegetables so healthy to eat.
