Spinal Cord Injuries Healed in Mice
Jul-08-10
Japanese researchers have been successful in repairing damaged spinal cords of mice using induced pluripotent stem cells (iPS), giving new hope to human victims.The problem with iPS cells has been that they ca grow uncontrollably, causing tumors in the treated areas.
The researchers got around this problem by transplanting the iPS cells into mice brains, then harvesting the cells that had not formed tumors and injecting them into the damaged spinal cord.
The mouse, which had lost all mobility in his hind legs nine days previously, was soon able to use its legs.
