摘要:
The technology described herein is directed to compositions and cell culture media for increasing the lifespan of neutrophils. Also described are methods and kits for culturing neutrophils using the compositions or cell culture media. Such cultured neutrophils can be used to treat disorders such as neutropenia or microbial infections.

A method for producing non-human conditionally immortalized mast cell progenitors comprises: introducing a nucleic acid molecule comprising an inducible homeobox gene into myeloid progenitor cells, wherein said myeloid progenitor cells are derived from a non-human animal and are engineered to express a heterologous high-affinity IgE receptor alpha subunit (FcεRIα); and selecting for cells which contain the nucleic acid molecule. The non-human conditionally immortalized mast cell progenitors may be cultured to obtain differentiated mast cells. The mast cells find utility in assays for the determination of IgE mediated allergies.

In one aspect, a method of treating a subject having or at risk of having graft-versus-host disease (GvHD) generally includes administering to the subject a plurality of myeloid-derived suppressor cells (MDSCs) effective to ameliorate at least one symptom or clinical sign of graft-versus-host disease compared to a suitable control subject. In another aspect, a method of treating a tumor in a subject generally includes administering to the subject an anti-tumor therapy and co-administering to the subject an inflammasome inciting agent in an amount effective to increase inflammasome activation of MDSCs sufficiently to reduce suppressor function of the MDSCs.

Methods and compositions for differentiating tissue resident multipotent mesenchmal stromal cells (MSCs) such as adipose tissue resident MSCs into a hematopoietic lineage are described.
摘要:
The present invention relates to the in vitro production of erythrocytes/granulocytes and to the treatment of myelodysplastic syndrome using a method for inducing hemoblast differentiation. The present invention provides a media composition comprising gelsolin as an active ingredient for inducing the differentiation of hematopoietic precursor cells into erythrocytes/granulocytes, and a pharmaceutical composition comprising gelsolin as an active ingredient for treating myelodysplastic syndrome. Since the composition of the present invention improves the efficiency of differentiation of hematopoietic precursor cells into erythrocytes/granulocytes while maintaining a low rate of occurrence of cell dysplasia and having the effect of improving the enucleation rate and cell survivability, the present invention can be effectively used for producing erythrocytes/granulocytes in vitro and for treating myelodysplastic syndrome.

The present invention relates to a method for producing human eosinophils from human pluripotent stem cells. More specifically, the present invention provides a method for producing human eosinophils from human pluripotent stem cells, which method comprises the steps of: (1) co-culturing, in the presence of VEGF, human pluripotent stem cells with cells separated from the AGM region of a mammalian fetus; (2) performing suspension culture using a medium comprising IL-3, IL-6, Flt3 ligand, SCF, TPO and serum; (3) performing suspension culture using a medium comprising IL-3, SCF, GM-CSF and serum; and, optionally, (4) performing suspension culture using a medium comprising IL-3, IL-5 and serum.

The present invention has an object to solve the problem in a method for separating nucleated cells from a cell-containing fluid using a cell separation filter. Specifically, the present invention provides a cell separation filter and a method for preparing cells using a cell separation filter, which are capable of reducing unnecessary cell contamination in a nucleated cell fraction without needs of designing non-woven fabrics to suit cell species to be recovered. The present invention also provides a cell separation filter and a method for preparing cells using the filter capable of improving the recovery yield of nucleated cells. The present invention provides a cell separation filter comprising: a container having an inlet and an outlet, an adsorbent filled in the container, and a partition having an opening, the partition separating the adsorbent. The present invention also provides a method for preparing nucleated cells including the steps of: introducing a cell-containing fluid through the inlet of the cell separation filter to contact the cell-containing fluid with the adsorbent; and recovering a nucleated cell fraction from the filter.

A method for efficient generation of neutrophils, eosinophils, macrophages, osteoclasts, dendritic cells an Langerhans cells from human embryonic stem cells is disclosed.
摘要:
The present invention provides a complex of an antigen and IgE binding to the antigen, a composition including an antigen and IgE binding to the antigen, and a method of using the complex or the composition. With the present invention, it is possible to induce naive T cells to develop into Th2 cells. Moreover, the present invention clarified a working mechanism of a Th2-type immune response, particularly a production mechanism of early IL-4. With use of the present invention, it is possible to provide a technique of treating and preventing Th2-type diseases.
