I have never seen anything like this before. Good work! They found a completely new difference between normal brain, benign tumors and malignant tumors of the brain. The physical properties which allow the Glioblastoma to spread into the normal brain is just a physical property of the tumor cells. We need to target that is some way. Perhaps the proteins that cause this property can be targeted, or the microenvironment can be targeted. Perhaps Optune could be used to stop movement of the cells as the movement of cells can be disrupted by alternating electrical fields, but unfortunately these fields would have to be on 100% of the time to totally disrupt the tumor cells and that is difficult with Optune. It only works while it is turned on, and most people only use it 70-95% of the time.
