Dispersion of Pluripotent Stem Cells, and Pluripotent Stem Cell Product and Method for Producing Same

Abstract

An object of the present invention is to provide a dispersion of pluripotent stem cells and a pluripotent stem cell product having a suitable quality as a pharmaceutical or a raw material for producing a pharmaceutical which can be stored and distributed, and a method for producing the same. The method for producing a pluripotent stem cell product of the present invention comprises (1) culturing pluripotent stem cells in an undifferentiation maintenance medium; (2) suspending the pluripotent stem cells cultured in step (1) in a first medium for suspending cells containing a ROCK inhibitor; (3) replacing the medium for suspending cells of a suspension obtained in step (2) with a medium for cryopreservation to obtain a cell dispersion solution consisting of the medium for cryopreservation and the pluripotent stem cells dispersed in the medium for cryopreservation; and (4) filling the cell dispersion solution obtained in step (3) into an airtight container so as to be in an airtight state.
