Abstract:

Osteoarthritis (OA) is a chronic degenerative disease which commonly occurred in dogs. Although there are many treat options, they can only relieve symptoms, but not can modify the disease. Moreover, conventional treatment has limitations because of its adverse events. Therefore, it is necessary that development of Disease Modifying OA Drugs (DMOADs) with low adverse effects. To evaluate the effects of Membrane-Free Stem Cell Extract (MFSCE) on the clinical signs and cartilage regeneration of OA dogs. Thirty privately owned dogs with OA were separated into two groups; placebo treated group (n=6), MFSCE treated group (n=22). All dogs were injected MFSCE or placebo once a week for 4 weeks in intra-articular. To evaluate the symptoms, dogs and owners were visit hospital at day 0, 7, 14, 21, and 28. The effect of MFSCE on pain relief was evaluated using pain score and pain at palpation score. Both symptoms were improved in MFSCE treated group while no significant changes in placebo treated group after 4 weeks treatment. The effect of MFSCE on physical function improvement was evaluated using behavior score, standing score, walking score, lameness score, and weight bearing score. All symptoms were improved in MFSCE treated group while no significant changes in placebo treated group after 4 weeks treatment. The effects of MFSCE on joint structure were evaluated using radiographic score. Joint structure was improved in MFSCE treated group while no significant changes in placebo treated group after 4 weeks treatment. There were no changes on general symptoms, symptoms of lesion, adverse events or general symptoms that can be occurred by injection, hematological parameter, and urinal parameters. Overall, these results, MFSCE could be the first-in-class DMOAD.
