Abstract

In one embodiment of the present invention, a method is provided for making a physiologically active and biocompatible cellular implant for implantation into a host body. The method includes the steps of: (a) forming first and second layers of first and second polymer solutions, respectively, each layer having a first substantially uncross-linked surface and an opposing second cross-linked surface; (b) forming a sandwich of a cell suspension layer of physiologically active cells in a substantially uncross-linked third solution between the first and second, and (c) cross-linking the first and second polymer solutions in a direction toward the cell suspension layer, thereby forming a cellular implant. In another embodiment, all polymer solutions initially are uncross-linked and sequentially spread in layers followed by cross-linking.
