Umbilical Cord-Derived Mesenchymal Stem Cells Inhibit Cadherin-11 Expression by Fibroblast-Like Synoviocytes in Rheumatoid Arthritis

Figure 5

UCMSC prevented tissue damage in CIA. (a) The severity of CIA was progressively attenuated in UCMSC treated rats, as compared with PBS and FLS treated rats. . (b) H&E-stained sagittal sections of joints from CIA rats. PBS and FLS treated rats showed a marked severe synovitis and cartilage erosion. However, the majority of joints from mice injected with UCMSC had normal morphology with a smooth articulation cartilage surface. Magnification, 100x. UCMSC: umbilical cord-derived mesenchymal stem cell; FLS: fibroblast-like synoviocytes; CIA: collagen-induced arthritis.
