Abstract:
PROBLEM TO BE SOLVED: To provide compositions and methods for minimally invasive systemic delivery of proteins including TGF-β-superfamily members.SOLUTION: The invention is directed to methods and compositions for systemic delivery of minimally soluble bioactive agents such as, but not limited to, TGF-β-superfamily proteins. According to the invention, an exemplary bioactive agent is BMP-7. The invention also provides minimally invasive systemic treatment of skeletal disorders such as osteoporosis. The invention also provides minimally invasive systemic treatment of damaged or diseased non-calcified tissues and organs such as kidneys. Practice of the invention eliminates adverse side effects at the sites of intravenous administration of the bioactive agent.
Abstract:
The present invention provides methods of repairing and regenerating cartilage tissue using a soluble morphogenic protein complex comprising (a) a morphogenic protein; and (b) a morphogenic protein pro region isolated from a morphogenic protein, or a conservative substitution variant or a fragment of said pro region, wherein said pro region or variant or fragment is noncovalently linked to the morphogenic protein, and wherein said complex is more soluble in an aqueous solvent than said morphogenic protein alone.
Abstract:
The present invention provides the use of a matrix-free composition lacking a scaffolding structure comprising an osteogenic protein dispersed in a biocompatible non-rigid, amorphous carrier having no defined surfaces for the preparation of pharmaceutical compositions for filling a defect locus, for repairing chondral or osteochondral defects or for accelerating cartilage formation at a defect locus.
Abstract:
PROBLEM TO BE SOLVED: To provide a treatment method and agent to be used for treatment of a mammal subject having a chronic renal failure, having a risk of chronic renal failure, or having need of renal replacement therapy.SOLUTION: The problem is solved by the treatment method provided herein, which includes the administration of specific protein or protein based thereon of osteogenic protein (OP)/bone morphogenetic protein (BMP) family of TGF-β superfamily; the administration of specific morphogenetic factors, inductive factors thereof, or corresponding morphogenetic factor receptor agonist; or transplanting of renal cell induced by using the morphogenetic factors. The useful morphogenetic factors are members of OP/BMP family proteins or proteins based thereon.
Abstract:
The present invention is directed to methods and compositions for accomplishing systemic delivery of minimally-soluble bioactive agents such as, but not limited to, proteins of the TGF-&bgr; superfamily via a peripheral mode of administration. According to the invention, an exemplary bioactive agent is BMP-7. The invention further provides for minimally-invasive systemic treatment of skeletal disorders such as osteoporosis as well as minimally-invasive systemic treatment of injured or diseased non-mineralized tissues and organs such kidneys. Practice of the invention eliminates adverse side effects at the peripheral site of intravenous administration of the bioactive agent.
