Document Type and Number:
WIPO Patent Application WO/2017/002422
Kind Code:
A1
Abstract:
In order to cut a plurality of clumps having substantially uniform shapes and dimensions out of a propagated cell aggregate and appropriately eliminate contamination by fragments of different shapes or dimensions, when cutting a plurality of clumps having substantially uniform shapes out of a propagated cell aggregate, a cutting line for cutting out a clump of a specific shape is set such that the surface area of the peripheral part of the cell aggregate that will not be cut by the cutting line exceeds the surface area of an individual clump, and a laser beam is projected so as to scan the cutting line, and as a result thereof, the cell aggregate is cut.
