Abstract

The present invention provides pharmaceutical compositions comprising a morphogenic protein stimulatory factor (MPSF) for improving the tissue inductive activity of morphogenic proteins, particularly those belonging to the BMP protein family. Methods for improving the tissue inductive activity of a morphogenic protein in a mammal using those compositions are provided. This invention also provides implantable morphogenic devices comprising a morphogenic protein and a MPSF disposed within a carrier, that are capable of inducing tissue formation in allogeneic and xenogeneic implants. Methods for inducing local tissue formation from a progenitor cell in a mammal using those devices are also provided. A method for accelerating allograft repair in a mammal using morphogenic devices is provided. This invention also provides a prosthetic device comprising a prosthesis coated with a morphogenic protein and a MPSF, and a method for promoting in vivo integration of an implantable prosthetic device to enhance the bond strength between the prosthesis and the existing target tissue at the joining site. Methods of treating tissue degenerative conditions in a mammal using the pharmaceutical compositions are also provided.

Claims

1. A method for improving the tissue inductive activity of a morphogenic protein on a mammalian progenitor cell comprising the step of coadministering to the cell a morphogenic protein stimulatory factor (MPSF) selected from the group consisting of hormones, cytokines, peptides and growth factors, whereby the MPSF stimulates tissue induction by the morphogenic protein;

with the proviso that when 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.

2. The method according to claim 1, wherein the MPSF has an additive effect on stimulating tissue induction by the morphogenic protein.

3. The method according to claim 1, wherein the MPSF has a synergistic effect on stimulating tissue induction by the morphogenic protein.

4. The method according to claim 1, wherein the morphogenic protein is an osteogenic protein that is capable of inducing the progenitor cell to form endochondral or intramembranous bone.

5. The method according to claim 1, wherein the morphogenic protein is an osteogenic protein that is capable of inducing the progenitor cell to form cartilage.

6. The method according to claim 1, wherein the morphogenic protein is an osteogenic protein that is capable of inducing the progenitor cell to form tendon/ligament-like or neural tissue.

7. The method according to claim 1, wherein the morphogenic protein comprises a polypeptide selected from the group consisting of:

BMP-2, BMP-4, BMP-5, BMP-6, OP-1 (BMP-7), BMP-8, BMP-9, BMP-10, BMP-11, BMP-12, and BMP-13, COP-5 and COP-7.

8. The method according to claim 1, wherein the morphogenic protein comprises a disulfide bonded dimeric species comprising a polypeptide selected from the group consisting of OP-1, BMP-2, BMP-4 and BMP-6.

9. The method according to claim 1, wherein the morphogenic protein comprises OP-1.

10. The method according to claim 1, wherein the morphogenic protein is produced by the expression of a recombinant DNA molecule in a host cell.

11. The method according to claim 1, wherein the morphogenic protein stimulatory factor comprises at least one compound selected from the group consisting of:

insulin-like growth factor I (IGF-I), estradiol, growth hormone (GH), growth and differentiation factor (GDF), hydrocortisone (HC), insulin, progesterone, parathyroid hormone (PTH), vitamin D, retinoic acid and IL-6.

12. The method according to claim 1, wherein the MPSF is administered in an amount capable of synergistically stimulating the ability of the morphogenic protein to induce tissue formation in the mammal.

13. The method according to claim 1, wherein the morphogenic protein stimulatory factor comprises an agent that increases IGF-I bioactivity in the mammal.

14. The method according to claim 1, wherein the morphogenic protein is present at a concentration of at least about 1 ng/ml, and the morphogenic protein stimulatory factor is present at a concentration of at least about 0.01 ng/ml.

15. The method according to claim 1, wherein the morphogenic protein comprises OP-1 at a concentration of from about 1 ng/ml to about 500 ng/ml and the morphogenic protein stimulatory factor comprises IGF-I at a concentration from about 0.1 ng/ml to about 50 ng/ml.

16. The method according to claim 1, wherein the morphogenic protein comprises OP-1 at a concentration of from about 1 ng/ml to about 500 ng/ml and the morphogenic protein stimulatory factor comprises estradiol at a concentration of from about 0.05 nM to about 1000 nM.
