Abstract
The present invention provides a biological bandage, comprising an envelope enclosing cells which secrete biologically active cellular products such as growth factors, which promote the healing of wounds. The envelope is further comprised of a permeable bottom membrane through which the cellular product diffuses, and a top membrane. Preferably the bandage has a separator interposed between the two membranes. This invention also relates to a method for treating wounds. The bandage provides a continuous, uniform source of fresh cellular product.
