Abstract: In a process of fabricating a tissue array, a tissue block is sliced to obtain sheet-form pieces of tissue, and each of the sheet-form pieces is closely rolled around a guide member to form a spiral shape tissue around the guide member. Then, the spiral shape tissues are inserted in an axial direction into holes arrayed in a base block.

Abstract: A tissue piece forming device suitable for forming a tissue piece required in the process of fabricating a novel tissue array chip having many benefits such as the one that the tissue array chip can be fabricated even if the tissue included in a tissue block has a small thickness. The tissue piece forming device (100) for forming a sheet-like tissue piece (S) into a roll shape includes a rotary shaft (1) to which one end of the sliced tissue piece (S) is secured and a drive means for rotating the rotary shaft (1). The tissue piece (S) can be formed into a tight roll shape while rotating the rotary shaft (1).

Abstract: [Task] 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.

Abstract: [Problems] It is intended to provide a storing device which is convenient in preserving a slice of a pathological tissue or the like over a long time and by which a required number of slices can be quickly provided without waste. It is also intended to provide an instrument for microscopic observation which is equipped with this storing device and a transparent plate having an adhesive layer formed thereon. [Means for Solving Problems] A device comprising: a piece of a resin film on which a slice having been excised from a sample block or a cell block slice is adhered and fixed via an adhesive layer provided on the surface thereof; and a holder on the surface of which the back face of the film piece is detachably adhered and fixed via a pressure-sensitive adhesive layer. An instrument for microscopic observation which comprises the storing device and a transparent plate for adhering and fixing the film piece having been peeled off from the storing device.
