Definitions
- Embryonic development in mammals commences with a series of cleavage divisions that generates equivalent totipotent cells. Maternal factors deposited in the oocyte dictate a characteristic number and timing of cleavages for each species. Activation of the zygotic genome occurs during the cleavage process. This is followed by the divergence of two distinct cell lineages, an outer epithelial cell layer, the trophectoderm, and an internal cluster of cells, the inner cell mass (ICM) . The trophectoderm subsequently contributes the embryo- derived component of the placenta, whereas the ICM is the founder of the embryo proper.
- ICM inner cell mass
- the present invention provides a combination of transplantation of a nucleus from a somatic cell into an enucleated oocyte with identification of daughter cells of the oocyte that express a gene characteristic of a desired stem cell .
- somatic cell of the predetermined species which cell contains a gene coding for a marker which is differentially expressed in (a) desired stem cells, and (b) cells other than desired stem cells;
- a selection/reporter gene, ?geo is integrated by homologous recombination into the sox2 gene, which is expressed uniformly in precursor cells in the neural plate and neural tube.
- a transgene containing this construct is introduced into somatic cells, and application of G41 8 after nuclear transplantation results in the efficient isolation of viable ?geo-positive cells.
- These cells express markers of neuroepithelial precursor cells. They can be propagated and will differentiate efficiently into networks of neuron-like cells that express a variety of neuronal markers.
- an in vitro system for genetic and molecular dissection of mammalian neural differentiation is provided by the invention, and also a route for the production of pure populations of normal or genetically modified neural precursors and neurons for functional studies including transplantation.
- the technology of the present invention is of application to all mammalian cell types, and to obtaining embryonic stem cells of a species for which there is a low (or no) availability of recipient oocytes. It is preferred that the somatic cell is a human cell, and surprisingly the invention provides for creation of human embryonic stem cells from a non-human oocyte - pig or cow oocytes are used in the recited examples below, as they are readily available.
