- the processing device 100 is used to perform processing for handling cells or cell culture samples using a holding member 10 having at least one holding portion for holding cells or cell culture samples.
- the type of cells is not particularly limited, but may be, for example, human-derived iPS cells (induced pluripotent stem cells).
- the cell culture sample is not particularly limited, but may include, for example, water, culture medium, artificially synthesized peptide solution, cell adhesive, etc.
- FIG. 2 is a perspective view showing an example of the configuration of the holding member 10.
- the holding member 10 is a device for forming a pattern of cells or cell adhesive on the culture surface of a culture substrate (not shown).
- the cells include cell aggregates such as colonies formed by cell aggregation.
- the holding member 10 has a plurality of columnar structures 12 arranged on the surface of the substrate 11.
- the columnar structures 12 are an example of a "holding section" in the disclosed technology.
- Each of the columnar structures 12 has a columnar structure whose axial direction is perpendicular to the main surface of the substrate 11.
- the axial length of the columnar structures 12 is not particularly limited, but may be, for example, 1 mm or more and 100 mm or less.
- the culture substrate is a substrate on which a pattern of cells or cell adhesive is formed by the holding member 10, and is a substrate having a culture surface on which cells are cultured.
- the culture substrate may be, for example, a well plate having a plurality of wells, and the culture surface may be, for example, the bottom surface of each of the plurality of wells provided in the well plate.
- the plurality of columnar structures 12 may be provided corresponding to the plurality of wells provided in the well plate.
- FIG. 1 illustrates a configuration including 48 columnar structures 12 provided corresponding to each well of a well plate having 48 (6 ⁇ 8) wells.
- the arrangement form of the columnar structures 12 (the number of rows and columns and the arrangement interval) is not limited to the example illustrated in FIG. 1, and is appropriately determined according to the arrangement of the cell pattern to be formed on the culture substrate.
- Each of the columnar structures 12 has a holding surface 13 at its tip for holding a liquid.
- the liquid held on the holding surface 13 is typically a cell suspension or a cell adhesive.
- the pattern formed on the culture surface of the culture substrate by the holding member 10 reflects the planar shape of the holding surface 13.
- Figure 1 shows an example of a holding surface 13 with a circular planar shape. The shape of the holding surface 13 is determined appropriately according to the pattern of cells or cell adhesive to be formed on the culture substrate.
- the columnar structure 12 is preferably configured such that at least the holding surface 13 is made of a hydrophobic (water-repellent) material.
- a hydrophobic (water-repellent) material By configuring the holding surface 13 of a hydrophobic (water-repellent) material, the amount of liquid that can be held on the holding surface 13 can be increased. This makes it possible to form a relatively large-sized pattern of cells or cell adhesive on the culture surface of the culture substrate.
- the holding surface 13 of the columnar structure 12 is preferably configured of a material having a contact angle with water of 45° or more.
- the columnar structure 12 is preferably resistant to high-pressure steam sterilization treatment, i.e., heat-resistant.
- At least the holding surface 13 of the columnar structure 12 may be configured of a resin.
- polyacetal can be suitably used as the material of the columnar structure 12 (holding surface 13).
- the columnar structure 12 may be configured of the same material as the substrate 11 and may be integrated with the substrate 11.
- the holding member 10 is placed so that the holding surface 13 of the columnar structure 12 faces vertically upward. At this time, the holding surface 13 is horizontal ( Figure 3A).
- a cell suspension or cell adhesive is dropped onto each holding surface 13 of the columnar structures 12 to form a droplet 20 of the cell suspension or cell adhesive so as to form an air-liquid-solid interface on the outer edge of the holding surface 13 (FIG. 3B).
- the cell suspension or cell adhesive is dropped onto the holding surface 13 using a pipette 50 and a processing device 100 (see FIG. 1). The configuration and method of use of the processing device 100 will be described later.
- the cell suspension or cell adhesive is an example of a "cell or cell culture sample" in the disclosed technology.
- the pipette 50 is an example of an "object that accesses the holding portion" in the disclosed technology.
- the droplet 20 is brought into contact with the culture surface 32 of the culture substrate 30 with the holding surface 13 on which the droplet 20 is formed facing vertically upward (Fig. 3C). That is, the droplet 20 is brought into contact with the culture surface 32 by placing the culture substrate 30 over the columnar structure 12 from above. This causes the cell suspension or cell adhesive held on the holding surface 13 to adhere to the culture surface 32 of the culture substrate 30.
- the culture substrate 30 may be a well plate having a plurality of wells 31. In this case, the bottom surface of each of the wells 31 serves as the culture surface 32.
- Each of the plurality of columnar structures 12 provided on the holding member 10 corresponds to each of the plurality of wells 31 provided on the culture substrate 30.
- the columnar structures 12 and the wells 31 are aligned horizontally with the bottom surface of the wells 31 facing downward. Thereafter, while maintaining the culture surface 32 horizontal, the culture surface 32 is gradually brought closer to the holding surface 13, and each of the droplets 20 formed on the holding surface 13 of each of the multiple columnar structures 12 is brought into contact with the bottom surface (culture surface 32) of each of the multiple wells 31 in a batch process.
- the size of the pattern formed on the culture surface 32 can be controlled by the distance between the holding surface 13 and the culture surface 32 when the droplet 20 is brought into contact with the culture surface 32.
- the distance between the holding surface 13 and the culture surface 32 when the droplet 20 is brought into contact with the culture surface 32 is determined according to the size of the pattern to be formed on the culture surface 32.
- a pattern of cell suspension or cell adhesive that reflects the planar shape of the holding surface 13 is formed in a batch process on the bottom surface (culture surface 32) of each of the multiple wells 31.
- Extracellular matrix proteins such as vitronectin, laminin, fibronectin, collagens, and gelatins can be used as cell adhesives.
- cells 40 are seeded on the culture surface 32 (FIG. 3F).
- the cells 40 are seeded by injecting a cell suspension adjusted to a predetermined cell concentration into each well 31.
- the type of cells 40 is not particularly limited as long as the cells 40 are adhesive cells.
- the cells 40 may be, for example, human-derived iPS cells.
- Cells 40 adhere to the areas of culture surface 32 that are coated with cell adhesive 21. Then, by culturing cells 40 in an appropriate environment, cells 40 proliferate in the areas coated with cell adhesive 21. As a result, a cell pattern 41 that corresponds to the pattern of cell adhesive 21 is formed on culture surface 32 ( Figure 3G).
- the holding member 10 and the pattern forming method form a pattern whose size corresponds to the size of the droplets 20 formed on the holding surface 13, making it possible to form a relatively large pattern.
- the processing device 100 will be described below.
- the processing device 100 is used, for example, in a process (see FIG. 3B) for forming a droplet 20 on the holding surface 13 of the holding member 10 using a pipette 50.

- FIG. 5 is a perspective view showing the configuration of the cover portion 120 alone.
- FIG. 6 is a perspective view showing the configuration of the auxiliary portion 130 alone.

- the protective surface 121 is parallel to the mounting surface 111 of the base portion 110. In other words, when the holding member 10 is mounted on the base portion 110, the protective surface 121 faces the holding surface 13 of the columnar structure 12.
- the side surface 122 and the back surface 123 are perpendicular to the mounting surface 111 of the base portion 110.

- the area of the region 124 surrounded by the dotted line in FIG. 5 corresponds to the planar area of the section in which the columnar structures 12 of the holding member 10 are arranged.
- the entire holding member 10 can be accommodated in the space 140 surrounded by the protective surface 121, side surface 122, rear surface 123 of the cover part 120, and the mounting surface 111 of the base part 110 (i.e., the space formed below the protective surface 121).
- the shape of the protective surface 121 is a rectangle or square with sides along the X direction and sides along the Y direction.
- the holding member 10 is mounted on the base part 110 so that the arrangement direction of the columnar structures 12 is along the X direction and the Y direction (i.e., parallel to each side of the protective surface 121).
- the protective surface 121 has a first fixing structure 125 for fixing the pipette 50 to the side along the X direction (arrangement direction of the columnar structures 12) on the open end side (front side) of the cover part 120.
- the first fixing structure 125 is composed of a plurality of grooves (or notches) 126 provided along the X direction. The multiple pipettes 50 engage with each of the grooves (or notches) 126, so that the multiple pipettes 50 are fixed in a position relative to the holding surface 13.
- each pipette 50 is positioned at a position corresponding to each of the columnar structures 12 arranged along the X direction.
- the auxiliary part 130 is a member that assists in fixing the pipette 50 to the protective surface 121.
- the auxiliary part 130 has a first part 131 that extends along the X direction, and a second part 132 that is connected to both ends of the first part 131 in the X direction and extends along the Z direction.
- the second part 132 is fastened to the side of the cover part 120 by a screw 135 (see FIG. 1), so that the first part 131 is supported so as to be positioned above the first fixing structure 125 of the protective surface 121.
- the first part 131 has a second fixing structure 133 that sandwiches the pipette 50 between itself and the first fixing structure 125 provided on the protective surface 121.
- the second fixing structure 133 is composed of a plurality of grooves (or cutouts) 134 arranged along the X direction. Like the plurality of grooves (or cutouts) 126 that constitute the first fixing structure 125, the plurality of grooves (or cutouts) 134 that constitute the second fixing structure 133 are arranged at the same intervals as the arrangement intervals of the columnar structures 12 in the X direction, and are arranged at positions corresponding to the plurality of grooves (or cutouts) 126 that constitute the first fixing structure 125.
- the pipette 50 engages with the groove (or notch) 126 constituting the first fixing structure 125 and also engages with the groove (or notch) 134 constituting the second fixing structure 133, so that the pipette 50 is sandwiched between the first fixing structure 125 and the second fixing structure 133, as shown in FIG. 1.
- One of the cover part 120 and the base part 110 can move relative to the other along the Y direction. That is, when the holding member 10 is mounted on the base part 110, one of the protective surface 121 and the columnar structures 12 can move relative to the other along the arrangement direction of the columnar structures 12.
- the base part 110 and the holding member 10 are kept stationary, and the cover part 120 and the auxiliary part 130 move in the Y direction.
- the pipette 50 moves together with the cover part 120 and the auxiliary part 130. Note that the cover part 120, the auxiliary part 130, and the pipette 50 may be kept stationary, and the base part 110 and the holding member 10 may move in the Y direction.
- the processing device 100 has a positioning mechanism that positions the relative positions of the cover part 120 and the base part 110 in the direction of their relative movement (in other words, the relative positions of the protective surface 121 and the columnar structures 12).
- the positioning mechanism is composed of wheels 150 (see FIG. 7) connected to the protective surface 121 and a number of recesses 114 (see FIG. 4 and FIG. 8) that engage with the wheels 150.
- FIG. 7 is an X-Z plan view of the cover part 120 and the base part 110, viewed from the open end side of the cover part 120.
- the cover part 120 has wheels 150 attached to each of the two side surfaces 122. They are positioned inside the space 140 surrounded by the protective surface 121 and side surfaces 122 of the cover part 120 and the mounting surface 111 of the base part 110.
- both ends of the base part 110 in the X direction have guides 113 extending along the Y direction, which is the movement direction of the cover part 120.
- the guides 113 have a plurality of recesses 114 and protrusions 115 arranged along the Y direction. That is, the guides 113 have an uneven structure in which the recesses 114 and the protrusions 115 are continuous along the Y direction.
- the cover part 120 moves in the Y direction when the wheels roll on the guides 113.
- the wheels 150 engage with the recesses 114 the wheels 150 are sandwiched between the protrusions 115 at the front and rear, and the movement of the wheels 150 in the Y direction is suppressed. This allows the cover part 120 to move in the Y direction in stages, and allows the relative positions of the cover part 120 and the base part 110 in the Y direction to be determined.
- the recesses 114 are spaced apart at intervals equal to the spacing of the columnar structures 12 in the Y direction. This allows the position of the pipette 50, which moves together with the cover part 120 and the auxiliary part 130, in the Y direction to correspond to the arrangement of the columnar structures 12 in the Y direction. That is, when the wheel 150 is engaged with a recess 114, the pipette 50 is positioned in the nth row of the columnar structure 12 in the Y direction, and when the wheel 150 is engaged with the adjacent recess 114, the pipette 50 is positioned in the (n+1)th row of the columnar structure 12 in the Y direction.

- the pipettes 50 are engaged with the grooves (or notches) 134 constituting the second fixing structure 133 provided on the auxiliary part 130, thereby helping to fix each pipette 50 to the protective surface 121 (FIG. 9A).
- a holding member 10 having multiple columnar structures 12 is mounted on the mounting surface 111 of the base portion 110 ( Figure 9A).
- each pipette 50 moves integrally with the cover part 120.
- each pipette 50 is positioned at a position corresponding to each of the columnar structures 12 arranged in the first row in the Y direction.
- each of the columnar structures 12 arranged in the first row in the Y direction is positioned directly below the outlet of the corresponding pipette 50.
- liquid containing cells or a cell culture sample is ejected from each pipette 50.
- droplets 20 containing cells or a cell culture sample are formed in a batch process on the holding surface 13 of each of the columnar structures 12 arranged in the first row in the Y direction ( Figure 9B).
- each pipette 50 moves integrally with the cover part 120.
- each pipette 50 is positioned at a position corresponding to each of the columnar structures 12 arranged in the second row in the Y direction.
- Each of the columnar structures 12 arranged in the first row in the Y direction is covered with a protective surface 121. This prevents foreign matter from being mixed into the droplets 20 held on the holding surface 13 of each of the columnar structures 12 arranged in the first row in the Y direction.
- liquid containing cells or a cell culture sample is ejected from each of the pipettes 50.
- droplets 20 containing cells or a cell culture sample are formed in a batch process on the holding surface 13 of each of the columnar structures 12 arranged in the second row in the Y direction (FIG. 9C).
- the cover part 120 is moved one step at a time in the Y direction, and droplets 20 are formed sequentially on the holding surface 13 of each of the columnar structures 12 arranged in each row. After the droplets 20 are formed, each of the columnar structures 12 is covered with the protective surface 121 by the movement of the cover part 120. This prevents foreign matter from being mixed into the droplets 20 ( Figure 9D).
- each of the columnar structures 12 is covered with the protective surface 121 after the droplet 20 containing the cells or cell culture sample is formed. Therefore, according to the processing device 100 and the processing method using the same in accordance with an embodiment of the disclosed technology, it is possible to prevent the intrusion of foreign matter into the cells or cell culture sample in a process of handling the cells or cell culture sample using a holding member 10 having a plurality of columnar structures 12 that hold the cells or cell culture sample.
- a plate or dish having a plurality of wells can also be used as a holding member as a holding part for holding cells or cell culture samples.
