XENOTRANSPLANTATION OF CELLS USING BIODEGRADABLE MICROCAPSULES

We have designed a microcapsule system with controllable biodegradability which allows breakdown and absorption of implants when the cells die or become functionally inactive. These results may have application to other alginate-PLL encapsulation systems. The ability to cross species lines using these biodegradable microcapsules has the potential to expand dramatically the number of patients and the scope of diseases that can be successfully treated with cellular therapy.
