摘要:
The present invention relates to a method for preparing an embryonic stem cell (ESC)-like cell, which comprises the steps of: (a) obtaining a first cell population from a mammalian tissue or body fluid, wherein the first cell population comprises adult stem cells; (b) obtaining a second somatic cell population from a mammalian tissue, wherein the mammalian tissue is different from the mammalian tissue in step (a) and the second cell population is different from the first cell population; (c) coculturing the first cell population and the second cell population in a medium for a period of time sufficient to form a colony from either the first cell population or the second cell population; and (d) subculturing a cell from the colony in a medium for a period time sufficient to prepare the ESC-like cell.
摘要:
A method of generating a population of cells useful for treating a nerve disease or disorder in a subject, the method comprising up-regulating a level of at least one exogenous mi RNA in mesenchymal stem cells (MSCs) and/or down-regulating a level of at least one mi RNA using a polynucleotide agent that hybridizes to the mi RNA, thereby generating the population of cells useful for treating the nerve disease or disorder. Isolated populations of cells generated thereby and uses thereof are also provided.
摘要:
Human progenitor T cells that are able to successfully engraft a murine thymus and differentiate into mature human T and NK cells are described. The human progenitor T cells have the phenotype CD34+CD7+CD 1a-CD5- or CD34+CD7+CD1a-CD5+ and are derived from human hematopoietic stem cells, embryonic stem cells and induced pluripotent stem cells by coculture with cells expressing a Notch receptor ligand (OP9-DL1 or OP9-DL4). Such cells are useful in a variety of applications including immune reconstitution, the treatment of immunodeficiencies and as carriers for genes used in gene therapy.
摘要:
The present invention is a method and kits for generating a homogenous population of hematopoietic progenitor cells capable of differentiating into a hematopoietic cell lineage. Whereas the combination of Homeobox-B8 protein and FMS-like tyrosine kinase 3 ligand generate cells with the potential to differentiate into different myeloid and lymphoid cell types, Homeobox-A7 protein and erythropoietin generate cells with the potential to differentiate into erythropoietic or thrombopoietic cell types.
摘要:
The invention relates to induction of reprogramming of somatic cells, by methods which require mild growth conditions. Disclosed are methods of inducing dedifferentiation of mesenchymal stromal cell (MSC), by seeding or incubating mesenchymal stromal cells (MSCs) at low density, and without introduction or expression of exogenous genes in the cells.
摘要:
The invention provides methods for treating myelodysplasia syndrome (MDS). The invention is generally directed to reducing certain overt symptoms and disease-causing biological events in MDS by administering certain cells to a subject having MDS. The invention is also directed to drug discovery methods to screen for agents that modulate the ability of the cells to affect these events. The invention is also directed to cell banks that can be used to provide cells for administration to a subject, the banks comprising cells having desired potency for affecting these events.
摘要:
The present invention relates to the in vitro and ex vivo culture of leukemia initiating cells (LICs). This has utility in various applications, such as screening for candidate agents for treating leukemia, identifying leukemia patients likely to respond to a candidate agent for treating leukemia, monitoring a leukemia patient for drug resistance, e.g. chemoresistance, to an agent, predicting the prognosis of a leukemia patient and determining the ability of a therapeutic agent to reduce the proportion of LICs in a leukemic patient.
摘要:
A method of generating a population of cells useful for treating a nerve disease or disorder in a subject, the method comprising up-regulating a level of at least one exogenous miRNA in mesenchymal stem cells (MSCs) and/or down-regulating a level of at least one miRNA using a polynucleotide agent that hybridizes to the miRNA, thereby generating the population of cells useful for treating the nerve disease or disorder. Isolated populations of cells with an astrocytic phenotype generated thereby and uses thereof are also provided.
