  • Publication number: 20100095388
    Abstract: The subject of the present invention is to provide a means to producing an erythropoietin-producing organoid using mesenchymal stem cell derived from a mammal. It is a method for producing erythropoietin-producing organoid (organ-like structure) precursor, comprising the step of transplanting mesenchymal stem cell derived from a mammal into an embryo within a pregnant mammalian host or an embryo separated from a pregnant mammalian host to thereby induce the differentiation of the mesenchymal stem cell, in particular, a site to which the mesenchymal stem cell is to be transplanted is a nephrogenic site of the embryo, and a timing of transplantation corresponds to the stage in which a immune system of the host is still immunologically tolerant.

  • Publication number: 20090304639
    Abstract: The present invention provides a means for achieving generation of a complex organ such as kidney and the like through the use of hMSCs to generate the human organ. The method for preparing a desired organ for transplantation to human by transplanting an isolated human mesenchymal stem cell to the embryo of a pregnant mammal host to induce differentiation of the mesenchymal stem cell is a method wherein the mesenchymal stem cell is transplanted into the embryo at a corresponding site for differentiation into the desired organ in the host at a transplantation time when the host is still at an immunologically tolerant stage.

  • Publication number: 20090186004
    Abstract: The present invention provides a method for preparing an organ, particularly a kidney, for transplantation into mammals. In detail, the present invention provides a method for preparing autotransplantation of autologous organs, particularly a kidney, wherein the isolated autologous mesenchymal stem cells are transplanted into an embryo inside a pregnant mammalian host or into an embryo dissected from a pregnant mammalian host at a desired site to induce differentiation, which is then transplanted into the individual.

  • Patent number: 6788990
    Abstract: A process control device controls a plurality of processing devices placed in parallel to perform at least two process steps for consecutively processing workpieces in a lot. The process control device includes a device group information for grouping of a plurality of processing devices into a plurality of device groups. For example, when the workpieces are semiconductor devices, processing devices having identical deviating characteristics are grouped into the same group to perform a plurality of photolithographic steps. The process control device further includes a device group selecting unit for selecting the device group such that the lot is processed in the second process step using a processing device included in the same device group as a processing device used in the first process step.

  • Patent number: 6577972
    Abstract: In a sampling inspection managing system, for each processing step, a setting is made on a processing flow table as to whether the processing step concerned is a step for determining the sampling inspection frequency of a specific inspection step. For a processing step which is set as “being a step for determining the sampling inspection frequency”, the inspection frequency of the specific inspection step is set on a sampling frequency setting table for every kind of product to be processed. Further, for the processing step, the processing number of lots is counted for every kind of product in a count table, and, on the basis of the processing number thus counted, a judgment is made as to whether each lot is a lot to be inspected in the specific inspection step. The judgment result is stored as information for the lot in a lot table. Accordingly, the inspection can be carried out at an inspection frequency suitable for every kind of product.

  • Patent number: 6535778
    Abstract: In a process control method, when T1+Tw+T2<Td is satisfied, where a time obtained by adding a conveyance time from a hold stocker to the pre-treatment processing equipment to a waiting time until start of a pre-treatment is T1, treatment time in the pre-treatment processing equipment is Tw, storage time from completion of the process in the pre-treatment processing equipment to starting of charging into a post-treatment is T2, and treatment time in the post-treatment equipment is Td, a point of time TR1 when the treatment of a lot 1 is started in the post-treatment equipment is utilized as a trigger, and a lot 2 is charged after a predetermined standby time Ta1 so that a point of time when the treatment time Td of the lot 1 has been completed in the post-treatment equipment may almost coincide with the point of time when the treatment time Td of the lot 2 is started in the post-treatment equipment.

  • Publication number: 20020120357
    Abstract: An efficient process control method capable of performing a lot treatment within a preliminarily specified time without idle condition of a post-treatment apparatus at a treatment stage in which the specified time until start of charging the lot pre-treated in a pre-treatment processing equipment into a post-treatment equipment. The process control method improves productivity.
