Embryonic stem cells kill cancer

Researchers Use Human Embryonic Stem Cells To Kill Cancer Cells
For the first time, stem cell researchers at the University of Minnesota have coaxed human embryonic stem cells to create cancer-killing cells in the laboratory, paving the way for future treatments for various types of cancers (or tumors). The research will be published in the Oct. 15 issue of the Journal of Immunology.

Undifferentiated human embryonic stem cells can be used to make blood cells like natural killer cells or red blood cells

Researchers generated "natural killer" cells from the human embryonic stem cells. As part of the immune system, natural killer cells normally are present in the blood stream and are play a role in defending the body against infection and against some cancers.

"This is the first published research to show the ability to make cells from human embryonic stem cells that are able to treat and fight cancer, especially leukemias and lymphomas," said Dan Kaufman, M.D., Ph.D., assistant professor of medicine in the Stem Cell Institute and Department of Medicine at the University of Minnesota and lead author of the study.
Note especially this comment:
This research was done on two of the federally approved embryonic stem cell lines. Kaufman said, however, that if the research would lead to a treatment for people, new lines would have to be developed.
Too bad we have a Federal government that refuses to support this.
