Abstract:

This disclosure relates to compositions and methods for encapsulating biomaterials such as cells to prevent immune responses. In certain embodiments the disclosure relates to capsules comprising a cell or cells gelled in alginate coated with a layer that prevents migration of immune molecules to the cell surface and an outer capsule layer comprising non-immunogenic material optionally containing immunosuppressive agents. In certain embodiments, the cells are capable of generating insulin that emanates from the capsule.
