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.

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 myelodysplastic 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:
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+CD1a−CD5− or CD34+CD7+CD1a−CD5+ and are derived from human hematopoietic stem cells, embryonic stem cells and induced pluripotent stem cells b\ 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:
A method of generating astrocytes is disclosed, the method comprising up-regulating miR-101 and down-regulating miR-138 using an agent which hybridizes to the miRNA in mesenchymal stem cells (MSCs). Isolated cell populations and uses thereof are also disclosed.
摘要:
The present invention relates to a three-dimensional (3D) model of a hematopoietic stem and progenitor cell (HSPC) niche, that comprises the coculture of human HSPC and human mesenchymal stromal cells in a defined 3D environment and thereby procures vital stem cell functions.

摘要:
The purpose of the present invention is to provide a method for producing a regenerative organ primordium for transplantation, said regenerative organ primordium for transplantation ensuring continuity with a recipient after transplantation and facilitating transplantation procedures. Provided is a method for producing a regenerative organ primordium provided with a guide for transplantation, said method comprising: a step for preparing a regenerative organ primordium by tightly contacting a first cell mass, which substantially consists of mesenchymal cells, with a second cell mass, which substantially consists of epithelial cells, and culturing these cell masses within a supporting medium; and a step for inserting the guide into the regenerative organ primordium.
