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.

PDX1 pancreatic endoderm cells in cell delivery devices and methods thereof

Disclosed herein are methods of producing pancreatic hormone-expressing cells by first differentiating pluripotent cells in cell culture so as to produce endodermal cells, the endodermal cells being competent to further differentiate into hormone-expressing cells capable of secreting at least one pancreatic hormone in response to a physiological signal, and then, transplanting the cultured endodermal cells into an organism, such as an organism in need of an endocrine cell therapy.

Methods of producing pancreatic hormones

This disclosure relates to compositions comprising human preprimitive streak cells and/or human mesendoderm cells as well as methods for their production. Additionally, disclosed herein are methods of identifying factors useful in the further differentiation of preprimitive streak and mesendoderm cell types.

Methods of making human primitive ectoderm cells

The present invention relates to a cryopreserved in vitro cell culture comprising human pancreatic progenitor cells that co-express pancreatic-duodenal homeobox factor-1 (PDX1) and NK6 homeobox 1 (NKX6.1) and are chromogranin negative. The present invention also relates to a method for cryopreserving an in vitro population of human pancreatic progenitor cells that co-express PDX1 and NKX6.1 and are chromogranin negative.

Cryopreserved in vitro cell culture of human pancreatic progenitor cells

Disclosed are devices and methods for transplanting cells, such as pancreatic endoderm cells, into a host. The devices include a non-woven fabric external to a cell-excluding membrane, and the non-woven fabric and/or cell-excluding membrane can be perforated. Treatment of the host with immunosuppressive reagents, required to inhibit allograft rejection due to perforations in the cell delivery device, does not compromise maturation or function of transplanted pancreatic endoderm cells.

Disclosed herein are methods for cryopreserving, hibernation and room temperature storage of PEC aggregates, implantable semipermeable devices and the VC combination product.

Cryopreservation of encapsulated pancreatic endoderm cells

Methods of lowering blood glucose levels in a mammal

The present invention relates to a perforated semi-permeable device comprising, human pancreatic endocrine cells or human PDX1-positive pancreatic endoderm cells contained within a semi-permeable membrane comprising a synthetic material, wherein the synthetic material is polysulfone (PSF), nano-fiber mats, polyimide, tetrafluoroethylene/polytetrafluoroethylene (PTFE), expanded polytetrafluoroethylene (ePTFE), polyacrylonitrile, polyethersulfone, acrylic resin, cellulose acetate, cellulose nitrate, polyamide, or hydroxylpropyl methyl cellulose (HPMC), a cell encapsulation chamber, and at least one seal that is within the cell encapsulation chamber.

Encapsulation of pancreatic cells derived from human pluripotent stem cells

Described herein are methods for implanting cells into a host comprising the steps of implanting into the host a device comprising a cell encapsulation chamber with at least one seal, allowing the device to vascularize, and loading the device with a human embryonic stem (hES) cell-derived pancreatic progenitor cell population.

The present invention relates to methods for encapsulating pancreatic progenitors in a biocompatible semi-permeable encapsulating device. The present invention also relates to production of human insulin in a mammal in response to glucose stimulation.
