Cell enclosure device and use for same

An organ-type chip system comprising:

• at least two of
• a tissue-type chip comprising a cell enclosure device for constructing a multicellular structure obtained by culturing cells, comprising a porous membrane in at least a portion of the cell enclosure device in which one type of cells is enclosed or a tissue-type chip comprising a cell enclosure device for constructing a multicellular structure obtained by culturing cells, comprising a porous membrane in at least a portion of the cell enclosure device in which one type of cells is enclosed, wherein a density of the cells is 2.0/103 cells/mL or more and 1.0×109 cells/mL or less, or
• an organ-type chip comprising a cell enclosure device for constructing a multicellular structure obtained by culturing cells, comprising a porous membrane in at least a portion of the cell enclosure device in which at least two types of cells are enclosed or
• an organ-type chip comprising a cell enclosure device for constructing a multicellular structure obtained by culturing cells, comprising a porous membrane in at least a portion of the cell enclosure device in which at least two types of cells are enclosed, wherein a density of the cells is 2.0×103 cells/mL or more and 1.0/109 cells/mL or less,
• wherein the tissue-type chips or the organ-type chips are connected while maintaining a cell enclosure property.
