PROBLEM TO BE SOLVED: To develop a monocyte-affinity material simply and inexpensively recovering monocytes in high purity and yield in a closed system, to provide a selective monocyte separating device and a device for culturing the monocytes using the monocyte-affinity material, to provide a method for a treatment with the same and to provide the monocytes and dendritic cells obtained by the method. SOLUTION: The monocyte separating material is prepared by using the monocyte-affinity material having a sugar structure or the device filled with the separating material is provided. The method for separating the monocytes is characterized as capturing the monocytes using the monocyte separating material or device and recovering the captured monocytes with a solution of the same kind of sugar used in the monocyte separating material at high concentration. The method for preparing the dendritic cells comprises culturing the resultant monocytes and differentiating and inducing the monocytes into the dendritic cells. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a material for selecting and separating monocytes which selects and separate the monocyte from a raw material cell fluid and further suppresses the lymphocyte contamination, a device and an apparatus using the monocyte selecting and capturing material, its processing method, and a method for producing dendritic cells using the obtained monocytes. SOLUTION: A raw material cell fluid containing monocytes is processed using a monocyte selecting and capturing material composed of a porous body over 60 μm in mean pore diameter, and a device using the monocyte selecting and capturing material, so that monocytes can be selectively separated from the raw material cell fluid.

PROBLEM TO BE SOLVED: To provide a method for activation of NK cells having nonspecific cytotoxic activity or ADCC activity to various tumor cells, virus-infected cells or the like, safely and easily proliferating without hybridizing with K562 or the like, and a method for proliferation of NK cells using the same and a method for producing cells and mononuclear cells comprising extensive NK cells. SOLUTION: The invention relates to the method for activation of NK cells comprising activation of the NK cells by imparting stimulation on the mononuclear cells containing T cells and the NK cells by a CD52 agonist. The stimulation by the CD52 agonist is carried out in the presence of cytokines. COPYRIGHT: (C)2007,JPO&INPIT
摘要:
The present invention it was determined that dendritic cells could be derived from various sources including peripheral blood monocytes in the presence of only GM-CSF without other cytokines if the monocytes were not activated. By preventing activation, such as by preventing binding of the cells to the surface of the culture vessel, the monocytes do not require the presence of additional cytokines, such as IL-4 or IL-13, to prevent differentiation into a non-dendritic cell lineage. The immature DCs generated and maintained in this manner were CD14− and expressed high levels of CD1a. Upon maturation by contact with an agent such as, for example, BCG and IFNγ, the cells were determined to express surface molecules typical of mature dendritic cells purified by prior methods and cultured in the presence of GM-CSF and IL-4. The mature dendritic cells produced from monocytes without activation and cultured in GM-CSF alone are suitable for use in dendritic cell-based immunotherapy methods, such as for use in the treatment of disease, including cancer.
