Abstract: Provided herein are, inter alia, methods of assaying neuronal progenitor cell populations derived from iPSCs, thereby providing for a user friendly molecular diagnostic tool for neuronal cell types, including dopaminergic neurons. The methods provided are valuable for the efficient and precise characterization of identity and functionality of iPSC-derived dopaminergic neurons prior to their clinical application such as the treatment of Parkinson's disease or Multiple Sclerosis.

Abstract: Disclosed are compositions and methods for classifying stem cells. The disclosure provides a way to define cells using a computational analysis.

Abstract: An isolated mammalian extraembryonic endoderm-like cell line is provided. Methods for producing isolated mammalian extraembryonic endoderm-like cell line derived from a mammalian pluripotent stem cell culture are provided. Primate or human embryonic stem cells (ESCs) spontaneously generate the primate or human extraembryonic endoderm-like cell line wherein the extraembryonic endoderm-like cells sustain the pluripotence of the primate or human ESCs.

Abstract: A method of treating Alzheimer's disease provides for administering NSC to a susceptible individual. Preferably the NSCs are administered intracisternally. Other administration routes are spinal injection, ventricular injection or systemic injection. Preferably, the quantity of NSC administered is in a range of about 400,000 to about 40,000,000. More preferably, the quantity of NSC is about 1,000,000 to about 10,000,000. The NSCs are administered at multiple locations. The NSCs can be administered to the neocortex or other affected areas of both hemispheres. The method of preventing further deterioration in cognitive function in a person diagnosed with Alzheimer's disease provides for administering NSC to the person in sufficient quantity to prevent additional loss of cognitive function.

Abstract: The present invention relates to a composition comprising a plurality of cDNAs which are differentially expressed in disorders of the brain, particularly Alzheimer's disease and which may be used in their entirety or in part as to diagnose, to stage to treat or to monitor the treatment of a subject with a brain disorder.

Abstract: The invention provides cDNAs that are diagnostic of and participate in neuronal differentiation and morphogenesis, proteins encoded by the cDNAs and agonists, antagonists, and antibodies that specifically bind the protein. The invention also provides compositions containing cDNAs, proteins, or antibodies and methods for their use diagnostically and therapeutically.

Abstract: The invention provides a Down syndrome critical region 1-like 1 protein, its encoding cDNAs, and antibodies that specifically bind the protein. The invention also provides for the use of these compositions in the diagnosis, prognosis, treatment and evaluation of progression and treatment of neurodegenerative disorders.

Abstract: A bigenic mouse is provided whose germ cells and somatic cells contain (i) inactive mouse TAU genes, and/or (ii) a transgene encoding the human TAU gene, with the transgene including all regulatory elements of the human TAU gene necessary for neuronal expression of the transgene in the bigenic mouse, and/or for human patterns of expression of the transgene in the bigenic mouse. The mice of the invention may contain one or two alleles for the human TAU gene (i.e., one or two TAU alleles). Mice of the invention are useful as a source of human Tau protein, and are useful as a model of Alzheimer's, Frontal Temporal Dementia and Parkinson's-like diseases.

Abstract: The invention provides a mammalian nucleic acid molecule and fragments thereof. It also provides for the use of the mammalian nucleic acid molecule for the characterization, diagnosis, evaluation, treatment, of conditions, diseases and disorders associated with gene expression and for the production of a model system. The invention additionally provides expression vectors and host cells for the production of the protein encoded by the mammalian nucleic acid molecule.

Abstract: The present invention provides an isolated population of non-mouse embryonic stem (ES) cells and methods of obtaining these ES cells. In one aspect, the target ES cells are obtained by co-culturing embryo cells from a target animal with non-target ES cells, such as mouse ES cells. In one embodiment, rat ES cells are isolated from the co-culture using positive or negative selectable markers.

Abstract: The present invention provides methods and compositions for transferring large transgene polynucleotides and unlinked selectable marker polynucleotides into eukaryotic cells by a novel method designated co-lipofection. The methods and compositions of the invention are used to produce novel transgenic non-human animals harboring large transgenes, such as a transgene comprising a human APP gene or human immunoglobulin gene.
