From the OHRI: Imagine removing blood or skin cells from a patient after a stroke, turning them into powerful stem cells in the lab, and then transplanting them back into the same patient’s brain so they can give rise to new neurons to repair the damage. This is the promise of induced pluripotent stem cell (iPSC) technology, and new research led by Dr. Jing Wang could help make it a reality. Dr. Wang and her team discovered that metformin, an established diabetes drug, can stimulate neural stem cells derived from iPSCs, helping them integrate into the brain and give rise to more neurons. In a stroke model, animals that received metformin-treated neural stem cells showed signs of increased regeneration in the brain and had faster recovery of gross motor skills compared to animals that received untreated cells. Future research will examine if other combinations of stem cells and drugs could be even better. See Stem Cells and Development for details.
