  • DEVICES AND METHODS FOR PRODUCTION OF CELL AGGREGATES
    Publication number: 20210355421
    Abstract: The present application provides methods and devices for the production and recovery of cell aggregates. In one embodiment, the device is a microwell device with a high density of microwells. The application also provides a device for extracting cell aggregates such as stem cells or embryoid bodies from well plates. Such cell aggregates are used for the differentiation of pluripotent stem cells such as embryonic stem cells, in the fields of developmental biology and regenerative medicine/tissue engineering.

  • DEVICES AND METHODS FOR PRODUCTION OF CELL AGGREGATES
    Publication number: 20100068793
    Abstract: A microwell device comprises a fluid vessel having a bottom region. A microwell plate is at the bottom region. The microwell plate comprises an upper region defining an upper plane. A plurality of microwells extend downwardly from the upper plane. Each of the microwells comprises an axis extending perpendicularly to the upper plane. Each of the microwells comprises a sidewall. The sidewall of at least one of the microwells has at least one wall component extending inwardly towards the axis.
