摘要

[PROBLEMS] To propose a method of producing a tissue array block, which can be produced even in the case of a tissue block having a small thickness, is little affected by tissue hardness, never suffers from a defect in a tissue piece or at the target site when processed into a tissue array chip, enables the collection of a tissue piece from a dispersed area, also enables the establishment of the position relationship between the inside of a tissue piece and the inside of a tissue block, and scarcely affects the utilization of the tissue block remaining after collecting the tissue piece; a method of producing a tissue array sheet; a tissue array block; a tissue array chip; a system of producing a tissue array block; and a system of producing a tissue array sheet. [MEANS FOR SOLVING PROBLEMS] Roll-shaped tissue pieces (t2) are produced by slicing a tissue block (B1). Then, the roll-shaped tissue pieces (t2) are inserted into a base block (B2) to give a tissue array block (B3). This tissue array block (B3) is sliced to give a tissue array sheet (S1) which is then mounted on a baseboard to give a tissue array chip (C1). The tissue pieces on this tissue array chip (C1) are in a spiral form.
