  • Method of in vitro differentiation of neural stem cells, motor neurons and dopamine neurons from primate embryonic stem cells
    Publication number: 20080206865
    Abstract: A method of differentiating embryonic stem cells into neural and motor cells is disclosed. In one embodiment, the invention comprises culturing a population of cells comprising a majority of cells that are characterized by an early rosette morphology and are Sox1?/Pax6+ in the presence of FGF2, FGF4, FGF8, FGF 9, or RA wherein the cells are characterized by an neural tube-like rosette morphology and are Pax6+/Sox1+.

  • Method of in vitro differentiation of transplantable neural precursor cells from primate embryonic stem cells
    Patent number: 6887706
    Abstract: A method of differentiating embryonic stem cells into neural precursor cells is disclosed. In one embodiment the method comprises the steps of (a) obtaining an embryonic stem cell culture, (b) propagating the stem cells, (c) forming embryoid bodies from the stem cells, and (d) culturing the embryoid bodies in a medium containing an effective amount of fibroblast growth factor 2, wherein neural precursor cells will be generated and isolated.
