Abstract: Objective To investigate the clinical effect of human neural stem cells transplantation on severe visual disability infants after cerebral palsy. Methods Cells obtained from the forebrain of an 11-week-old abortive fetus were cultured and expanded for 15 days, then injected into cerebral ventricle of 7 patients. Results Their vision of 4 patients improved, as well as changes of flash visual evoked potential and functional magnetic resonance imaging in a few days after transplantation. Conclusion Neural stem cells transplantation may benefit in some CP children with severe visual disability.
