  • CELL MICROSHEET, SYRINGE CONTAINING THE CELL MICROSHEET, AND PRODUCTION AND USE OF THE CELL MICROSHEET
    Publication number: 20220064592
    Abstract: Cell microsheets are formed from a culture of cells. The cell microsheets has a size that can pass through an injection needle with a certain thickness. The cell microsheets can be produced on a surface of a cell cultureware. A stimulus-responsive polymer is immobilized on the surface having small divisions of the cell cultureware. The cell microsheets are suitable for minimally invasive treatment.
