Methods of generating, repairing and/or maintaining connective tissue in vivo

1. A method of treating a disease in a human subject arising from degradation and/or inflammation of an avascular connective tissue that is rich in proteoglycans, comprising administering to the human subject a population of allogenic cells enriched for STRO-1+, tissue nonspecific alkaline phosphatase (TNAP)+multipotential precursor cells or progeny cells thereof, or both such cells,

a. wherein paracrine activities of the administered population of allogenic cells enriched for STRO-1+, TNAP+multipotential precursor cells or progeny cells thereof protect or stimulate growth or regeneration of the connective tissue that is rich in proteoglycans, or both,

b. wherein the disease is selected from the group consisting of tendonitis, back pain, rotary cuff tendon degradation, Carpal tunnel syndrome, De Quervain's syndrome, degenerative cervical and/or lumbar discs, intersection syndrome, reflex sympathetic dystrophy syndrome (RSDS), stenosing tenosynovitis, epicondylitis, tenosynovitis, thoracic outlet syndrome, ulnar nerve entrapment, radial tunnel syndrome, repetitive strain injury (RSI), osteoarthritis, rheumatoid arthritis, psoriatic arthritis, seronegative arthritis, arthritis associated with inflammatory bowel disease, ankylosing spondylitis, and a degenerated intervertebral disc disorder, and

c. wherein the population of allogeneic cells enriched for STRO-1+, tissue nonspecific alkaline phosphatase (TNAP)+multipotential precursor cells is, or progeny cells thereof are, or both are administered to a joint space.

2. The method of claim 1 , wherein the avascular connective tissue is cartilage.

3. The method of claim 2 , wherein the disease results in one or more defects in the cartilage.

4. The method of claim 3 , wherein the population of allogeneic cells enriched for STRO-1+, TNAP+multipotential precursor cells is not directly administered into the one or more defects in the cartilage.

5. The method of claim 1 , wherein the joint space is in a knee joint, a hip joint, an ankle joint, a shoulder joint, an elbow joint, a wrist joint, a hand or finger joint, a joint of the foot, or an intervertebral disc joint.

6. The method of claim 1 , wherein the population of allogeneic cells enriched for STRO-1+, tissue nonspecific alkaline phosphatase (TNAP)+multipotential precursor cells or progeny cells thereof, or both such cells are administered to the human subject by intra-articular injection.

7. The method of claim 2 , wherein the administration of the population of allogeneic cells enriched for STRO-1+, tissue nonspecific alkaline phosphatase (TNAP)+multipotential precursor cells or progeny cells thereof, or both such cells result in protection or stimulation of growth or regeneration of cartilage that is rich in proteoglycans.

8. The method of claim 7 wherein the cartilage that is rich in proteoglycans is hyaline cartilage.

9. The method of claim 1 , further comprising administering to the human subject hyaluronic acid (HA).
