Microphotographs showing the histological changes of hind ankle in hematoxylin and eosin (100 ×) stained sections. A and B: The histological picture of hind ankle joints of osteoarthritic rats treated with hyaluronic acid (HA); C and D: The histological picture of hind ankle joints of osteoarthritic rats treated with bone marrow mesenchymal stem cells (BMMSCs); E and F: Treated with BMMSCs + HA revealed improvements in the ankle joint articular tissue integrity and architecture with suppressed inflammation and reduced synovial membrane thickening.
