Methods of modulating bone remodeling
Disclosed herein, in certain instances, are methods of inhibiting osteoclast differentiation, bone resorption, bone formation, and bone remodeling in an individual in need thereof, comprising administering to the individual a composition comprising substantially fetal support tissue product including amniotic membrane and umbilical cord or an extract thereof, or a composition comprising substantially isolated HC-HA complex.
1. A method of inhibiting unwanted bone resorption in an individual in need thereof, comprising contacting a bone or joint characterized by unwanted bone resorption in said individual with a therapeutically-effective amount of a fetal support tissue that comprises: (a) cells, substantially all of which have been killed, and (b) HC-HA, thereby inhibiting unwanted bone resorption.
2. The method of claim 1 , wherein the fetal support tissue is placental amniotic membrane (PAM), umbilical cord amniotic membrane (UCAM), placenta, umbilical cord, chorion, amnion-chorion, or any combinations thereof.
3. The method of claim 1 , wherein the fetal support tissue is frozen or previously frozen.
4. The method of claim 1 , wherein the fetal support tissue is a sheet, powder, or homogenate.
5. The method of claim 1 , wherein the fetal support tissue is cryopreserved, lyophilized, terminally sterilized, or a combination thereof.
6. The method of claim 1 , wherein contacting a joint characterized by unwanted bone resorption with the fetal support tissue comprises injecting the fetal support tissue into the joint.
7. The method of claim 1 , wherein contacting a bone or joint characterized by unwanted bone resorption with the fetal support tissue comprises contacting the bone or joint with a medical device comprising the fetal support tissue.
8. The method of claim 1 , wherein the medical device is a patch, implant, orthopaedic prosthesis, or bone stent.
9. The method of claim 1 , wherein contacting a bone or joint characterized by unwanted bone resorption with the fetal support tissue comprises wrapping a fetal support tissue sheet around the bone or joint.
10. The method of claim 1 , wherein osteogenesis is promoted.
11. The method of claim 1 , wherein the unwanted bone resorption is associated with arthritis, osteoporosis, a bone tumor, Paget's Disease, alveolar bone degradation, or any combination thereof.
