Cell structure fixing and removing system

A cell structure removing tool of a cell structure fixing and removing system, the cell structure fixing and removing system comprising:

• an alignment base made of a silicone resin, the alignment base including a flat sticking surface to which needles with skewed cell aggregates are to be stuck;
• and
• the cell structure removing tool placed on the sticking surface between the alignment base and the cell aggregate,
• the cell structure removing tool including:
• a frame extending to correspond to an outline of the sticking surface, the frame including a puncture opening in middle, a bottom surface of the frame forming an alignment surface parallel to the sticking surface;
• and
• a porous sheet stretched and arranged on the alignment surface to close the puncture opening of the frame, the porous sheet allowing penetration by the needle,
• wherein an outline edge of the puncture opening in the alignment surface of the frame of the cell structure removing tool is located in the outline of the sticking surface.
