摘要

A process of fabricating a tissue array block; a process of fabricating a tissue array sheet; a tissue array block; a tissue array chip; a system of fabricating a tissue array block; and a system of fabricating a tissue array sheet are proposed, in which the tissue array block can be fabricated even in the case of that having a small thickness, is little affected by tissue hardness and, when having been processed into a tissue array chip, does not suffer any defect in a piece of tissue or at a site of interests, enables the collection of pieces of tissue from a dispersed area, also enables the establishment of positional 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 pieces of tissue.;[Solving means] A tissue block B1 is sliced to fabricate roll-shaped pieces of tissue t2. Then, the roll-shaped tissue pieces t2 are inserted into a base block B2 to give a tissue array block B3. The tissue array block B3 is sliced into tissue array sheets S1, which is then mounted on a substrate to give a tissue array chip C1. Pieces of tissue on the tissue array chip C1 are spirally shaped.
