Shots of brain cells restore learning, memory in rats
Technique may someday ease radiation-related side effects for cancer patients, study suggests
TRANSPLANT IN ACTION Scientists replaced brain cells destroyed in irradiated rats with ones grown from human stem cells. Here, the mature transplanted cells coat a neuron with insulation (green).
