( 23 were injected into intracranial glio...)Marrow-derived stem cells deliver new cytokine to kill brain tumor cells, offer protection

23 were injected into intracranial gliomas and other areas of the brain. Treated animals survived significantly longer than those in control groups. In fact, of those receiving BM-NSC-IL-23, 60 percent survived beyond day 120 tumor-free. Only 20 percent of those treated with IL-23 that was not attached to neural stem cells survived, and no animals survived if they received neural stem cells without IL-23.

Even after additional glioma cells were injected, BM-NSC-IL-23-treated animals remained tumor free, evidence of the long-term immunity provided by IL-23's generation of memory T-cells.
