  • Patent number: 6673603
    Abstract: The present invention provides the use and composition of matter of angiogenic or other growth factors expressed by combining various types and stages of differentiation of allogeneic human cell strains or lines in unencapsulated pastes (mixed with or applied to extracellular matrix material or synthetic biocompatible substances) to be temporarily applied to wounds or defects in the skin or other tissues for the restoration of blood supplying connective tissue to enable organ-specific cells to reestablish organ integrity as well as to inhibit excessive scar formation.
