Toxin-releasing stem cells kill brain tumors in mice
Harvard Medical School scientists have genetically engineered stem cells in lab that are capable of fighting brain tumors by secreting a toxin that destroys any cell that comes their way. The study was conducted on mice.
The stem cells have been engineered
to target a specific type of cancer cell and destroy it. This
breakthrough may lead to a potential cure of the deadly disease.
The neurosurgeons deliver the stem cells in thick gel that helps them in remaining in the desired area of the brain from where these cells have been engineered to attack certain types of cells instead of just attacking the healthy parts of the brain.
The small stem cells then make their way inside of the tumour cells and release the toxin which kills the infected tumour.
The cell produces a chemical known as Cytotoxin. Normally, this type of toxin will be harmful for the body. However, the researchers at Harvard Medical School have used it to make these deadly stem cells which act like highly specialized weapons.
Trials have been carried out on cancer infected mice suffering from Glioblastoma. The side effects of this treatment have not been determined yet. It will take years for this treatment to be approved for trials in humans.
