  • Methods for enhancing survival and/or proliferation of neural stem cells and neurite extension enhancers therefor pharmaceutical compositions containing neural stem cells assay methods and screening methods
    Patent number: 7785596
    Abstract: Methods for enhancing survival and/or proliferation of neural stem cells and pharmaceutical compositions containing neural stem cells prepared by such methods, together with methods for assaying factors enhancing survival and/or proliferation of neural stem cells and methods for screening for such factors. Either Galectin-1 is overexpressed in neural stem cells or neural stem cells are cultured in a liquid medium containing Galectin-1. Pharmaceutical compositions containing Galectin-1-overexpressing neural stem cells and pharmaceutical composition containing Galectin-1, prepared by the aforementioned methods, improve higher cerebral functions damaged by cerebral ischemia.
