摘要:
The present invention relates to methods for obtaining mesenchymal stem cells with improved cardiac regenerative potential. The methods comprise a step of co-culturing adult human mesenchymal stem cells with adult fully differentiated cardiomyocytes, which leads to a modulation of the cardioprotective secretome of the pre-conditioned mesenchymal stem cells. The invention also relates to pharmaceutical compositions comprising such pre-conditioned mesenchymal stem cells, and methods for using them for the treatment of cardiac pathologies and/or for cardiac tissue reconstructions or regeneration.
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 present invention relates to isolation of cardiovascular stem cells, and more particularly to cardiovascular stem cells positive for markers isll + /Nkx2.5 + /flkl + and cardiovascular stem cells which can differentiate along endothelial, cardiac, and smooth muscle cell lineages. The invention relates to uses of the cardiovascular stem cells, in particular for the treatment of cardiovascular disorders and as an assay comprising a plurality of cardiovascular stem cells. The invention also relates to a method for isolation and enrichment of stem cells using mesenchymal cell feeder layer and uses of mesenchymal feeder layer as a screening assay for agents which effect stem cells.
摘要:
Method to induce the differentiation of endothelial cells into cardiomyocites, comprising the co-cultivation of said endothelial cells with differentiated cardiomyocites.
摘要:
The invention features methods and compositions for treating damaged or scarred myocardial tissue, by transplanting mesenchymal stem cells into the damaged or scarred tissue.
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.
摘要:
Die Erfindung betrifft Materialzusammensetzungen, umfassend aus exokrinem Drüsengewebe erhaltene adulte Stammzellen und eine Trägermatrix in Form einer Fadenstruktur und/oder eines Netzes. Die Trägermatrix besteht vorzugsweise aus einem körperverträglichen und im Körper abbaubaren Kunststoffmaterial. Die erfindungsgemäßen Materialzusammensetzungen sind besonders geeignet zur Verwendung in der Regenerationsmedizin, z.B. zur Wiederherstellung von verletztem oder geschädigtem Myokardgewebe.
