Abstract: A multilayer culture vessel, comprising a culture vessel part and a reservoir part attached to the culture vessel part, wherein the culture vessel part comprises at least two culture trays that are stacked; the reservoir part comprises a surrounding wall defining an internal space and a port communicating with the internal space; the surrounding wall comprises a first surrounding wall part provided with the port and a second surrounding wall part facing the first surrounding wall part; the culture vessel part has openings communicating individual culture trays of the at least two culture trays with the internal space of the reservoir part; and the openings of the culture vessel part extend toward a first abutting portion that the first surrounding wall part abuts on the culture vessel part from a second abutting portion that the second surrounding wall part abuts on the culture vessel part.

Abstract: The present invention relates to a cell-based medicine comprising mesenchymal stem cells, and a method for producing the same. More specifically, the present invention relates to: a cell-based medicine containing mesenchymal stem cells, wherein a) the mesenchymal stem cells express CX3CL1 under stimulation with an inflammatory cytokine, and/or b) 90% or more of the mesenchymal stem cells express EGFR and/or ITGA4; and a method for producing a cell-based medicine containing mesenchymal stem cells, the method comprising the steps of: a) adding an inflammatory cytokine to a culture containing mesenchymal stem cells, and confirming that the mesenchymal stem cells express CX3CL1; and/or b) confirming that 90% or more of the mesenchymal stem cells express EGFR and/or ITGA4.

Abstract: The present invention relates to glucose dehydrogenase [NAD(P)+GDH] using nicotinamide adenine dinucleotide or nicotinamide adenine dinucleotide phosphate as a coenzyme, in which the thermal stability and/or the resistance to an organic solvent in the absence of sodium chloride are improved.
