Four and 8 weeks later performed a histological analysis of cartilage and the determination of the levels of Matrix Metalloproteinase-1(MMP-1) and Transforming growth factor β1 (TGF-β1) in serum by ELISA.</span></p> </div> <div> <p class="Pa6"><strong><span lang="EN-GB">RESULTS: </span></strong><span lang="EN-GB">The results showed that administration of MSC-WJ showed improvement in the histological picture of knee joints in experimental animals characterized by an increase in cartilage thickness on the joint surface. The administration of MSC-WJ showed a tendency to decrease MMP-1 serum levels of OA rats treated for 8 weeks, although statistically did not show a significant difference. Whereas, administration of MSC-WJ showed a decrease in serum levels of TGF-β1 OA rat treated for 8 weeks.</span></p> </div> <div><strong>CONCLUSION: </strong>MSC-WJ can repair damaged knee OA cartilage tissue. The administration of MSC-WJ can reduce serum levels of TGF-β1 OA rats treated for 8 weeks.</div>}, number={A}, journal={Open Access Macedonian Journal of Medical Sciences}, author={Endrinaldi, Endrinaldi and Ali, Hirowati and Tofrizal, Tofrizal and Asterina, Asterina and Elmatris, Elmatris and Yarni, Sisca Dwi}, year={2022}, month={Mar.}, pages={563–571} }
