Abstract: A novel cell culture method for inducing differentiation of a pluripotent stem cell into trophoblast and an automatic culture apparatus therefor includes: a first step of culturing the pluripotent stem cell in a presence of a ROCK inhibitor during a first time period; a second step of culturing the pluripotent stem cell, which has been subjected to the first step, without the ROCK inhibitor during a second time period following the first time period; and a step of culturing the pluripotent stem cell, which has been subjected to the second step, in the presence of the ROCK inhibitor during a third time period following the second time period, in which the pluripotent stem cell is cultured in a state of being adhered to a cell culture substrate including a planar mesh through the first to third time periods.

Abstract: The purpose of the invention is to provide novel cell culture substrates, cell culture vessels, and methods for cell culture. A cell culture substrate having a planar mesh structure, the substrate being coated with a polymer, is provided. Cells are cultured in a cell culture vessel having this substrate.

Abstract: A method for making a recombinant gene includes searching a database using a nucleotide sequence of a coding region, a nucleotide sequence that encodes an amino acid sequence, or an amino acid sequence, of a gene, for one or more nucleotide sequences having homology; selecting one or more nucleotide sequences other than nucleotide sequences only derived from a genome from the selected nucleotide sequences; for ones of the selected one or more nucleotide sequences comprising an upstream or downstream nucleotide sequence, analyzing whether the upstream or downstream nucleotide sequence is a functional sequence to select one or more first functional sequences; for ones of the selected one or more nucleotide sequences comprising no upstream or downstream nucleotide sequence, analyzing whether a gene information has any description indicating a functional sequence to select one or more second functional sequences; scoring the selected functional sequences; and selecting one or more functional sequences.

Abstract: There is the problem that a liquid culture medium fed by a pump has a high frequency of contact with a gas during movement in a tube, and the pH value of the liquid culture medium before and after feeding changes easily. In a liquid feeder and a cell culture apparatus provided therewith, a feed pipe 7 is connected with a gas bag 14, the liquid to be fed into the feed pipe 7 is fed so as to be sandwiched by a gas for suppressing the qualitative changes of the liquid. Furthermore, the gas bag is connected with a container 8 for holding a liquid, and holds the gas for suppressing qualitative changes of the liquid in a gas phase of the container.

Abstract: In culture vessels for producing biological samples, it is possible to prevent decrease in a temperature at the time of taking out the culture vessels from an automatic culture apparatus and during delivery of the culture vessels which have been taken out from the automatic culture apparatus. This invention includes a culture vessel 201 holding a biological sample therein, a heat storage portion 701 holding the culture vessel, and a heat insulation portion 601 surrounding the heat storage portion. The whole circumference or a part of 609, 610, and 611 of the heat insulation portion 601 is removable depending on an arrangement environment.

Abstract: There is provided a method for noninvasively evaluating the cell state (proliferation, multi-layering, and differentiation) of a cell sheet as a mimic tissue at the time of culturing the cell sheet. The method is characterized in that an analysis of an amino acid is conducted with the use of the culture supernatant of a cell sheet to monitor a change in the concentration of any amino acid selected from a group of 5-species of amino acids (Ile, Val, Ser, Leu, and Ala), thereby making a determination.

Abstract: A culture which maintains an aseptic state at the time of culturing is achieved, the avoidance of damage to a closed-system culture vessel and of an influence to the cells due to impacts and oscillation is possible during transportation after being manufactured. The closed-system culture vessel 101 has culture vessels 201, 202 for maintaining the cells and/or the culture medium, and a culturing space which is closed by holding members 203, 204 for holding the culture vessels, and the holding member has a semi-open cavity 221 independent of the culturing space. Further, the holding member, by being provided with a lid fixing ring 220 surrounding a connector part 214, is not damaged even when impacts are applied during transportation.
