  • Publication number: 20080267874
    Abstract: The present invention is related to human stem cells lines comprising a targeted gene construct, and in particular to human embryonic stem cells lines (hESC) comprising a reporter gene inserted into the Olig2 locus via homologous recombination. The hESC line remains pluripotent and maintains a normal karyotype, and allows for visualization of Olig2 expression by fluorescence microscopy and sorting by FACS. Since Olig2 is important is the development of motor neurons and oligodendrocytes, the present invention provides a means to study differentiation of stem cells into motor neurons and oligodendrocytes, as well as the study of intrinsic and extrinsic factors that affect such differentiation. The hESCs of the present invention also provide a means to study and determine optimal factors and conditions for cell differentiation.
