In each drawing, similar components are denoted by similar reference characters. The technical scope of the invention and the significance of terms described in Claims are not limited by contents described below.

(6) (Summary of Business Model)

(7) First, the summary of a business model according to the present invention will be described with reference to FIG. 1. FIG. 1 is a schematic view illustrating a business model and a system for an iPS cell bank according to an embodiment. The business model is a business model in which an iPS cell production site 30 receives a request to produce an iPS cell from a customer 10, accepts a somatic cell such as a blood cell from a collection institution 20, generates an iPS cell 32 from the accepted somatic cell, and evaluates the quality of the generated iPS cell 32, followed by stocking an iPS cell 33 conforming to a predetermined standard to an iPS cell stock site 40 and by transporting the iPS cell 33, by a transporting vehicle or aircraft, to the customer 10 depending on demand and charging the customer 10.

(8) Examples of the collection institution 20 include a hospital, a blood donation site, and another collection institution in which blood 22 which is a somatic cell can be collected from a donor 21 such as a patient. Such collection institutions 20 are established in plural bases (for example, Tokyo, Osaka, Fukuoka, and the like). The collection institution 20 collects the blood 22 from the donor 21 on a collection date of which notification is provided from the iPS cell production site 30, and ships the collected blood 22 on a shipping date of which notification is provided from the iPS cell production site 30. The shipped blood 22 is transported, by a transporting vehicle or aircraft, to the iPS cell production site 30 in the state of appropriately managing the temperature of the blood.

(9) Examples of the iPS cell production site 30 include a medical institution, a research institution, and another production institution in which the iPS cell 33 can be produced. The iPS cell production site 30 notifies the collection institution 20 of a collection date and an acceptance date automatically determined by a system 1 for an iPS cell bank to accept a somatic cell when making an entry of a production request from the customer 10. In such a manner, the collected blood is transported, by a transporting vehicle or aircraft, to the iPS cell production site 30.

(10) The iPS cell production site 30 produces the iPS cell 33 within a production period automatically determined by the system 1 for the iPS cell bank. The iPS cell production site 30 introduces an inducer into a collected blood cell 31 which is a somatic cell to generate the iPS cell 32, and conducts a test of the quality of the generated iPS cell 32 (differentiation-inducing property testing, gene mutation testing, fungal, bacterial, and viral testing, and the like) to produce the iPS cell 33 conforming to the standard. The iPS cell production site 30 ships the iPS cell 33 to a stock location automatically determined by the system 1 for the iPS cell bank, on a shipping date automatically determined by the system 1 for the iPS cell bank. The shipped iPS cell 33 is transported, by a transporting vehicle or aircraft, to the iPS cell stock site 40 in the state of appropriately managing the temperature of the iPS cell 33.

(11) Examples of the iPS cell stock site 40 include a warehouse, a medical institution, and another stock site in which the iPS cell 33 can be stocked. Such iPS cell stock sites 40 are established in plural bases (for example, Tokyo, Osaka, Fukuoka, and the like). The iPS cell stock site 40 cryopreserves the iPS cell 33 and regularly conducts thawing testing during a stock period automatically determined by the system 1 for the iPS cell bank, as well as carries out reconfirmation when the iPS cell 33 is used. The iPS cell stock site 40 transports the stocked iPS cell 33 to the customer 10 depending on demand. The transported iPS cell 33 is transported, by a transporting vehicle or aircraft, to the customer 10 in the state of appropriately managing the temperature of the iPS cell 33.

(48) (Operation of System for iPS Cell Bank)

(49) The operation of the system for iPS cell bank will now be described with reference to FIG. 4. FIG. 4 is a sequence diagram representing the operation of the system for the iPS cell bank according to the embodiment. Step S100 to step S106 may be carried out in any processing order.

(50) In step S100, an acceptance management terminal sends collectable dates, obtained from plural collection institutions, as well as collection institution IDs to a server apparatus. Then, in step S101, the server apparatus stores, in an entry table, the received collectable dates, as well as acceptance IDs and the collection institution IDs.

(51) In step S102, a production process management terminal sends, to the server apparatus, a producible period during which an iPS cell can be produced. Then, in step S103, the server apparatus stores, in a production process table, the received producible period during which the iPS cell can be produced, as well as a production ID.

(52) In step S104, a stock management terminal sends, to the server apparatus, stockable locations and stockable periods obtained from plural iPS cell stock sites. Then, in step S105, the server apparatus stores, in a stock table, the received stockable locations and stockable periods, as well as stock IDs and stock site IDs.

(53) In step S106, an entry management terminal receives a production request including first to third desired collection dates from a customer, as well as a customer ID. Then, in step S107, the entry management terminal sends, to the server apparatus, the received production request including the first to third desired collection dates, as well as the customer ID.

(54) Subsequently, in step S108, the server apparatus determines a date of collection of a somatic cell based on the first to third desired collection dates included in the received production request and on the stored collectable dates.

(55) The processing of step S108 will now be described in detail with reference to FIG. 3. The server apparatus extracts, from the acceptance table 102, a collectable date of a collection institution matching the first desired collection date (2018 Mar. 15) of a donor for an entry ID (0001). Because the collectable date matching the first desired collection date (2018 Mar. 15) does not exist in the acceptance table 102, the server apparatus extracts, from the acceptance table 102, a collectable date of a collection institution matching the second desired collection date (2018 Mar. 16) of the donor. Because the collectable date (2018 Mar. 16) matching the second desired collection date (2018 Mar. 16) exists in the acceptance table 102, the server apparatus determines the collectable date (2018 Mar. 16) as a collection date. When any collectable dates matching first to third desired collection dates do not exist in the acceptance table, the server apparatus provides notification of resetting of desired collection dates.

(56) Referring to FIG. 4, subsequently, in step S109, the server apparatus determines a production period for producing an iPS cell based on the determined date of collection of the somatic cell and on the stored producible period during which the iPS cell can be produced.

(57) The processing of step S109 will be described in more detail with reference to FIG. 3. For the entry ID (0001), the server apparatus adds a time of transportation of a somatic cell determined depending on a collection institution (for example, 1 day in the Tokyo collection site) to the determined collection date (2018 Mar. 16) to determine an earliest delivery date on which the somatic cell is delivered to the iPS cell production site earliest (2018 Mar. 17), and adds a quality preservable period during which the quality of the collected somatic cell can be preserved (for example, 2 days in the case of blood) to determine a latest delivery date on which the somatic cell is delivered to an iPS cell production site latest (2018 Mar. 18), whereby a deliverable period during which the somatic cell can be delivered from the collection institution to the iPS cell production site (2018 Mar. 17 to 2018 Mar. 18) is calculated. Then, the server apparatus extracts, from the production process table 103, the earliest producible period (2018 Mar. 16 to 2018 Sep. 16) of producible periods (2018 Mar. 16 to 2018 Sep. 16, and 2018 Mar. 17 to 2018 Sep. 17) overlapping with the calculated deliverable period (2018 Mar. 17 to 2018 Mar. 18), and determines a production period during which an iPS cell is produced (2018 Mar. 16 to 2018 Sep. 16). As a result, a period of production of an iPS cell is determined in consideration of the quality of a somatic cell, and therefore, a high-quality iPS cell can be stably supplied to a customer. “Production period” in this example means a period from the acceptance of a somatic cell in an iPS cell production site to the completion of the evaluation of the quality of an iPS cell, and includes not only a substantial period of generation of the iPS cell (3 months) but also a period of evaluation of the quality of the generated iPS cell (3 months).

(58) Referring to FIG. 4, in step S110, the server apparatus then determines an acceptance date on which the collected somatic cell is accepted in the iPS cell production site based on the determined date of collection of the somatic cell and on the determined period of production of the iPS cell.

(59) The processing of step S110 will be described in more detail with reference to FIG. 3. For the entry ID (0001), the server apparatus adds a time of transportation of the somatic cell (for example, 1 day in the Tokyo collection site) determined depending on a collection institution to the determined date of collection of the somatic cell (2018 Mar. 16) to determine an acceptance date (2018 Mar. 17), checks that the determined acceptance date (2018 Mar. 17) is within the period of production of the iPS cell (2018 Mar. 16 to 2018 Sep. 16), and determines a date of acceptance of the somatic cell (2018 Mar. 17).

(60) Referring to FIG. 4, in step S111, the server apparatus then determines a stock location and a stock period where the iPS cell is stocked based on the determined period of production of the iPS cell and on the stored stockable location and stockable period.

(61) The processing of step S111 will be described in more detail with reference to FIG. 3. For the entry ID (0001), the server apparatus adds a time of transportation of an iPS cell (for example, 1 day in the Tokyo stock site) determined depending on an iPS cell stock site to the date of the completion of the determined production period (2018 Sep. 16) to determine an earliest delivery date on which the iPS cell is delivered to the iPS cell stock site earliest (2018 Sep. 17), and adds a quality assurance period during which the quality of the produced iPS cell can be ensured (for example, 4 days in the case of preservation in liquid nitrogen) to determine a latest delivery date on which the iPS cell is delivered to the iPS cell production site latest (2018 Sep. 20), whereby a deliverable period during which the iPS cell can be delivered from the iPS cell production site to the iPS cell stock site (2018 Sep. 17 to 2018 Sep. 20) is calculated. Then, the server apparatus extracts, from the stock table 104, a stockable period (2018 Sep. 19 to 2068 Sep. 19) which is the earliest stockable period (2018 Sep. 19-2068 Sep. 19) of stockable periods (2018 Sep. 19 to 2068 Sep. 19, and 2018 Sep. 20 to 2068 Sep. 20) overlapping with the calculated deliverable period (2018 Sep. 17 to 2018 Sep. 20), and determines a stock period (2018 Sep. 19-2068 Sep. 19) and a stock location (for example, Tokyo stock site) where an iPS cell is stocked. As a result, a stock location and a stock period are determined in consideration of the quality of an iPS cell, and therefore, a high-quality iPS cell can be stably supplied to a customer.

(62) Referring to FIG. 4, in step S112, the server apparatus then determines a date of shipment of the produced iPS cell based on the determined period of production of the iPS cell and on the determined stock location and stock period.

(63) The processing of step S112 will now be described in detail with reference to FIG. 3. For the entry ID (0001), the server apparatus subtracts a time of transportation of an iPS cell determined depending on an iPS cell stock site (for example, 1 day in the Tokyo stock site) from the starting date (2018 Sep. 19) of the determined stock period to determine a shipping date (2018 Sep. 18), checks that the determined shipping date (2018 Sep. 18) is after the date of the completion of the production period (2018 Sep. 16), and determines a date of shipment of the iPS cell (2018 Sep. 18).

(64) Referring to FIG. 4, subsequently, in step S113, the server apparatus stores the determined information, i.e., the determined collection date, production period, date of acceptance of the somatic cell, stock location and stock period, and date of shipment of the iPS cell, in association with the customer ID.

(65) In step S114, the server apparatus sends the determined information, i.e., the determined collection date, production period, date of acceptance of the somatic cell, stock location and stock period, and date of shipment of the iPS cell, to the customer indicated by the customer ID.

(66) Following step S114, the server apparatus includes a step of registering the quality test result of the iPS cell, and a step of canceling the determined shipment of the iPS cell as represented in FIG. 3 when the registered quality test result of the iPS cell is inadequate.

(67) The operation-effect of the system for the iPS cell bank of the embodiment will now be described. A high-quality iPS cell can be stably supplied to a customer because the server apparatus determines a period of production of an iPS cell in consideration of the quality preservable period of a somatic cell (for example, 2 days in the case of blood) as described in the processing of step S109.

(68) A high-quality iPS cell can be stably supplied to a customer because the server apparatus determines a stock location and a stock period where an iPS cell is stocked in consideration of the quality assurance period (for example, 4 days in the case of preservation in liquid nitrogen) of an iPS cell conforming to a quality test as described in the processing of step S111.

(69) All of the programs according to the embodiment are recorded on a computer-readable non-transitory recording medium, for example, CD-ROM, and thus provided.

(70) The various embodiments have been described in the present specification. However, it should be understood that the present invention is not limited to the various embodiments described above, and various modifications can be made within the scope described in the following claims.
