Use of CXCL6 chemokine in the prevention or repair of cartilage defects
View Patent ↗The present invention disclosed the expression of CXCL6 by cells which are able to form stable cartilage. The invention describes the use of these cells and of CXCL6 to promote cartilage (and underlying bone) formation e.g. in the repair of cartilage or osteochondral defects. The invention further describes the use of chemokines in the modulation of progenitor cell differentiation.
1. A method for treatment of a cartilage or osteochondral defect comprising the step of administering an effective amount of Chemokine, CXC Motif, Ligand 6 (CXCL6) to an individual in need thereof, so as to obtain promotion of hyaline cartilage in said cartilage defect or in said osteochondral defect.
2. The method according to claim 1 , wherein said cartilage defect is a joint surface defect not related to inflammation.
3. The method according to claim 1 , wherein said CXCL6 is recombinant CXCL6.
4. The method according to claim 1 , wherein said CXCL6 is administered in a concentration gradient to said osteochondral defect.
5. The method according to claim 1 , further comprising the step of administering chondrogenic cells or precursor cells of said chondrogenic cells.
6. The method of claim 1 , said method comprising obtaining promotion of hyaline cartilage in said cartilage defect.
7. The method of claim 1 , said method comprising obtaining promotion of hyaline cartilage in said osteochondral defect.
8. The method of claim 7 , said method further comprising subchondral bone formation in said osteochondral defect.
