Effect of intraarticular injection of autologous adipose-derived mesenchymal stem and regenerative cells on clinical signs of chronic osteoarthritis of the elbow joint in dogs.

Autologous adipose-derived mesenchymal stem cell (AD-MSC) therapy involves harvesting fat from the patient, isolating the stem and regenerative cells, and administering the cells back to the patient. Autologous AD-MSC therapy in veterinary regenerative medicine has been commercially available since 2003. Previously reported results from a blinded, controlled trial in dogs with chronic osteoarthritis of the coxofemoral (hip) joint demonstrated efficacy of a single intraarticular injection of autologous AD-MSC therapy.
