2137275 9324627 PCTABScor01 The present invention provides a biological bandage (10), comprising an envelope (12) enclosing cells (16) which secrete biologically active cellular products (17) such as growth factors, which promote the healing of wounds. The envelope (12) is further comprised of a permeable bottom membrane (15) through which the cellular product (17) diffuses, and an impermeable top membrane (14). Preferably the bandage (10) has a separator (30) interposed betwen the two membranes. This invention also relates to a method for genetically engineering the cells (16), and a method for treating wounds. The bandage (10) provides a continous, uniform source of fresh, pure cellular product (17).
