  • Publication number: 20230233739
    Abstract: Disclosed are cell encapsulation devices and methods for transplanting cells, such as pancreatic endoderm cells, into a host. In some examples, a cell encapsulation can comprise a lumen configured to receive cells therein, a cell-excluding membrane, where the lumen is internal to the cell-excluding membrane, and a non-woven fabric layer external to the cell-excluding membrane, where the non-woven fabric layer and the cell-excluding membrane comprise perforations. The device can further comprise a woven mesh external to the non-woven fabric layer, where the non-woven fabric layer provides protection to the cell-excluding membrane from direct contact with the woven mesh.

  • Publication number: 20230165908
    Abstract: A human immature endocrine cell population and methods for making an immature endocrine cell population are provided. Specifically, immature beta cells and methods for production of immature beta cells are described. Immature beta cells co-express INS and NKX6.1 and are uni-potent and thereby develop into mature beta cells when implanted in vivo. The mature beta cells in vivo are capable of producing insulin in response to glucose stimulation.
