Growing More Natural Killer Cells

If we could introduce a very large number of active immune cells into the body for a short while, far more than the body generates by itself, we could solve a lot of problems - such as cancer. Here, a research team "demonstrated natural killer cells [derived] from human embryonic stem cells are better at killing human leukemia in mice, preventing the cancer from metastasizing in any of the animal's organs. The study has also shown stem cell-derived tumor-killing cells are highly effective in killing breast cancer, prostate cancer, testicular cancer and brain tumor cells. ... We've now proven that these cells are much more potent and effective at killing tumor cells than those coming from other sources like human umbilical cord blood, and we've been able to identify some of the reasons why. ... the next goal is to produce enough of the cells to treat humans, rather than mice. ... Based on the history of cell-based therapies at the university, I see this as very feasible. But it will take time based on the resources available to get to the scale of human treatments." You might also recall the similar GIFT immune therapy that produced very impressive results, but is presently buried beneath FDA regulatory requirements - as is all the most promising new biomedical technology.
