Tissue cells such as islet of Langerhans cells or liver cells are encapsulated within a spheroidal semipermeable membrane comprising a polysaccharide having acidic groups cross-linked with a polymer having a molecular weight greater than 3,000. The cells within the microcapsules are viable, healthy, physiologically active and capable of ongoing metabolism. The encapsulated cells are useful for implantation in a mammalian body to produce substances and effect chemical changes characteristic of the cells in vivo tissue.
