ABSTRACT:
The present invention provides the use and composition of matter of angiogenic or other growth/cytokine factors expressed by mixtures of allogeneic human cell strains or lines of various types and stages of differentiation. Also provided are unencapsulated preparations (mixed with or applied to extracellular matrix material or synthetic biocompatible substances) for the purpose of temporary application 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.
