    摘要: 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.

    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.

    摘要: 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.
