Cell Sorting Method and Cell Sorter

A cell sorting method using a fiber unit in which a plurality of fibers are bundled so as to be separable and unitable, the cell sorting method comprising the steps of:

• dispersing a cell group containing target cells targeted for sorting in a fluid into which the fiber unit is immersed;
• removing the non-target cells from non-target fibers to which non-target cells which are not targeted for sorting are attached or close among the plurality of fibers;
• and thereafter,
• proliferating the target cells by use of the fiber unit.

A cell sorting method using a fiber unit in which a plurality of fibers are bundled so as to be separable and unitable, the cell sorting method comprising the steps of

• respectively allocating coordinates to the fibers forming the fiber unit;
• dispersing a cell group containing target cells targeted for sorting in a fluid into which the fiber unit is immersed;
• designating the coordinates allocated to target fibers to which the target cells are attached among the plurality of fibers;
• separating the target fibers whose coordinates are designated, from the fiber unit;
• and
• proliferating the target cells by use of the separated target fibers.
