Cancer stem cells against cancer
Researchers Rogosin Institute in New York presented the results of their work and hope that fuels containing important new cancer stem cells being used to combat this disease itself.
The therapy, which will come in a week in phase two of the three that the study should be limited because the drugs can be introduced into the market, is to fill some capsules made of agarose with tumor cells of mice. These areas less than half a centimeter in diameter, are implanted in the person affected by cancer.
“When we fill the capsule with tumor cells, we realized that first of all grew up to occupy the inside to complete and then died so that they became small colonies of 100 or 150,” says Carlos Cordon Card, associate director all’Herbert Irving Comprehensive Cancer Center of the University ‘of Columbia in New York, who participated in the research.
Afterwards, the surviving (stem cells) to repopulate the areas. What ‘s been noticed and’ that the cells segregate factors that prevented the growth of other tumor cells. The study ‘was published in’ Cancer research ‘: an experiment with laboratory animals showing that implanting these areas in rats, cats and dogs suffering from cancer, could inhibit the development of cancer and, in some cases, these lead animal healing.
The positive results allowed to obtain approval from the Food and Drug Administration (FDA) for the initiation of the ‘Phase I’ which was attended by 30 patients with epithelial cancers (ovaries, pancreas, etc.) at a very advanced state. The results of the study will be published later this year. At the moment the data are positive, and researchers are preparing for the ‘Phase II’ which will include patients with prostate cancer and other solid tumors.
