Cell transplanting kit, cell transplanting device, and method for taking in transplant

A cell transplanting kit, comprising:

• a transplant including a cell group;
• and
• a cell transplanting device configured to place the transplant in a living body, wherein
• the cell transplanting device includes:
• a needle-shaped portion that extends in a shape of a tube and has an opening in a distal end portion of the needle-shaped portion;
• and
• an aspiration portion configured to aspirate an interior of the needle-shaped portion,
• the needle-shaped portion is configured to attract the transplant by aspiration by the aspiration portion and take the transplant into the interior through the opening, and is configured to, in a state in which the transplant has been taken in, have an inner diameter that is larger at a distal end of the needle-shaped portion and is reduced at a location between the distal end and a proximal end of the needle-shaped portion,
• the aspiration portion is configured to create an aspiration pressure in a range of −100 kPa to −0.1 kPa,
• the transplant includes a protection portion in a form of a gel covering at least a part of the cell group,
• the transplant has an outer diameter that is greater than or equal to a minimum value of the inner diameter of the needle-shaped portion, and
• the protection portion has a jelly strength of greater than or equal to 100 g.
