摘要:
The present invention relates to an in vitro model of chronic inflammation for use e.g. in pharmacological and toxicological studies and studies of development of chronic inflammation, type 2 diabetes and as a general model in basic and applied research.
摘要:
The current invention concerns a cell medium for in vitro inducing chondrogenesis or tenogenesis in mesenchymal stem cells (MSCs), whereby said medium comprises a glucose medium supplemented with at least one growth factor, said growth factor is chosen from the group of fibroblast growth factors (FGF) or the group of transforming growth factors (TGF), characterized in that said FGF or TGF is present in a total concentration of between 1 and 15 ng/ml. In both cases, IGF can be added to enhance the induction process. In a further aspect, the invention provides for a use of such cell medium as well as a method for inducing isolated mesenchymal stem cells (MSCs) and a cell composition obtained by such method.

摘要:
A method of expanding/maintaining undifferentiated hematopoietic stem cells by obtaining unselected mononuclear cells; and seeding the mononuclear cells into a stationary phase plug-flow bioreactor in which a three dimensional mesenchymal/stromal cell culture has been pre-established, thereby expanding/maintaining undifferentiated hematopoietic stem cells.
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:
The invention provides anti-inflammatory exosomes that, when administered locally or systemically, downregulate an inflammatory process in a subject in need of such treatment, as well as methods of making and using the anti-inflammatory exosomes.
摘要:
Methods of inducing a polarization of macrophages. The method includes obtaining a blood fraction, fractionating the blood fraction to produce a blood fraction, and contacting the blood fraction with a source of macrophages. A blood fraction including platelet-poor plasma polarizes the source of macrophages into M1 macrophages. A blood faction including a protein solution polarizes the source of macrophages into M2 macrophages.
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:
The present invention provides isolated immunomodulatory cells, populations, compositions and therapeutic uses thereof. The immunomodulatory cells of the invention have surprising efficacy in the immunomodulation of multiple sclerosis. In one embodiment said immunomodulatory cells are regulatory T-cells, in a particularly preferred embodiment said immunomodulatory cells are Foxp3+CD4+CD25+ T- reg and/or IL-10/TGF-.beta.- producing regulatory Trl cells. Methods for the preparation, expansion and/or generation of immunomodulatory cells of the invention comprises contacting a cell population comprising of MSC and/or fibroblast cells with PBLs in the presence of one or more multiple sclerosis-associated antigens.
