Neurosurgeons looking at stem cells from skin to fight brain tumors
...researchers successfully grew stem cells from skin samples
of adult patients with brain tumors. It is hoped that these cells can then be used as a new brain tumor therapy, which has been attempted successfully in mice. The Italian neurosurgeons made a presentation about their new study at the 54th annual m...
