C12N005/08

US Classification:

435/366000, 435/006000, 424/093210

Abstract:

A method of producing a homogenous population of homozygous stem (HS) cells pre-selected for immunotype and/or genotype from donor cells is described herein. The invention relates to methods of using immunohistocompatible HS cells for diagnosis, therapeutic and cosmetic transplantation, and the treatment of various genetic diseases, neurodegenerative diseases, traumatic injuries and cancer. The invention further relates to methods for using histocompatible HS stem cells pre-selected for a non-disease genotype for prophylactic and therapeutic intervention including, but not limited to, therapeutic and cosmetic transplantation, and the treatment of various genetic diseases, neurodegenerative diseases, and cancer. Furthermore, the invention relates to a catalogued transplant depository of HS cells derived from multiple donors, each of the HS cells being homozygous for a unique HLA haplotype, for the purpose of having a constant, reliable, comprehensive supply of immunohistocompatible cells for diagnosis, treatment and/or transplantation.

US Classification:

435/325000, 435/354000, 435/366000, 435/350000

Abstract:

The present invention discloses and describes pluripotent homozygous stem (HS) cells, and methods and materials for making same. The present invention also provides methods for differentiation of HS cells into progenitor (multipotent) cells or other desired cells, groups of cells or tissues. Further, the applications of the HS cells disclosed herein, include (but are not limited to) the diagnosis and treatment of various diseases (for example, genetic diseases, neurodegenerative diseases, endocrine-related disorders and cancer), traumatic injuries, cosmetic or therapeutic transplantation, gene therapy and cell replacement therapy.

International Classification:

C12Q001/68
G01N033/53

US Classification:

435/006000, 435/007200, 435/455000, 435/366000

Abstract:

The present invention relates to materials and methods for the quantitative and qualitative analysis of gene expression during targeted differentiation of isolated homozygous stem cells, and to materials and methods for accumulating sequence tags sampled from a population of expressed genes. More particularly, the present invention relates to a method for constructing a model of cellular development and differentiation comprising the steps of: (1) producing a homogenous population of homozygous stem (HS) cells; (2) directing the differentiation of the HS cells to arrive at desired mature (somatic) cells, group of cells or tissue; (3) periodically sampling HS cells undergoing differentiation to extract total cellular RNA produced at various sampling stages; (4) isolating mRNA from the total cellular RNA; and (5) constructing a cDNA library representative of proteins produced and expressed at various stages of differentiation, over the course of time. The present invention further relates to sequencing and cataloguing isolated mRNAs and cDNAs at various stages of differentiation of HS cells, producing and cataloguing isolated polypeptides sequences encoded by same, and screening the cDNA libraries. In vitro and in vivo cultures of homozygous stem cell are also described; such cultures find utility both as models of differentiation as well as sources of differentiated tissues and organs.
