Abstract: Provided is a cell collection apparatus includes: a supporter that supports a sheet to which a back surface of a substrate is pasted, the substrate being divided in to plural small pieces with a section of a tissue pasted on a front surface thereof; a needle including needle tips; and a holder that is configured to hold the needle with the needle tips facing the sheet on an opposite side to a substrate side of the sheet, and to move the needle in the forward direction of the needle tips, wherein at least two needle tips are arranged within a region narrower than the back surface of the small piece substantially on the identical plane intersecting with the longitudinal direction of the needle.

Abstract: To achieve a body-insertable apparatus such as a capsule endoscope that moves in a subject at a low speed at which acquisition of in-vivo information is sufficiently possible, the body-insertable apparatus is inserted into the subject and moves in the subject. The body-insertable apparatus includes an in-vivo information acquiring unit that acquires the in-vivo information, an external case member accommodating the in-vivo information acquiring unit, and a moving-speed suppressing unit positioned inside or outside of the external case member to generate a predetermined suppressing force for suppressing the moving speed between an inner wall of a passage route in the subject and the external case member.
