IMPLANTED BIOMATERIALS

Long-term viability through selective permeability

The cell-selective permeability of a retrievable microporous device encapsulating human therapeutic cells and implanted in the intraperitoneal space of mice provides long-term protection to the transplanted cells by dampening foreign-body responses and preventing the immune rejection of the graft.
