  • Cell culture method and automatic cell culture apparatus
    Patent number: 11926845
    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.

  • CELL SHEET CUTTING ASSISTANCE SYSTEM, CELL CULTURE SYSTEM AND CELL SHEET CUTTING ASSISTANCE METHOD
    Publication number: 20230407228
    Abstract: A cell sheet cutting assistance system comprises a processor for executing a program and a storage device for storing the program. The processor: receives, as input, an evaluation standard of a cell sheet and quality information of a cultured cell sheet; determines whether the quality information satisfies the evaluation standard; and outputs a cutting position of the cell sheet based on a result of the determination.
