1. A pharmaceutical composition for inducing tissue formation in a mammal, comprising:

  • a) a morphogenic protein capable of inducing tissue formation when accessible to a progenitor cell in the mammal;

    b) a morphogenic protein stimulatory factor (MPSF) capable of stimulating the ability of the morphogenic protein to induce tissue formation from the progenitor cell; and

    c) a pharmaceutically acceptable carrier;

    wherein the MPSF is selected from the group consisting of hormones, cytokines, peptides and growth factors; and

    provided thatwhen the progenitor cell is an osteoblast stimulated to form bone and the morphogenic protein is activin, the MPSF may not be estrogen or calcitonin;

    when the progenitor cell is an osteoblast stimulated to form bone and the morphogenic protein is a BMP homodimer or TGF-β

    , the MPSF may not be FGF, IGF-II, PDGF, estrogen, calcitonin, or vitamin D;

    when the progenitor cell is an osteoblast stimulated to form bone or cartilage and the morphogenic protein is a BMP homodimer, the MPSF may not be TGF-β

    ; and

    when the progenitor cell is an osteoblast stimulated to form bone and the morphogenic protein is a homodimer of BMP-2 or BMP-3, the MPSF may not be parathyroid hormone.
