ENG and rheumatoid arthritis: Additionally, the cell surface marker CD73 has been shown to enhance immunosuppression by reducing inflammatory molecules in both B‐cells and hMSCs, useful in treating autoimmune disorders like rheumatoid arthritis.45, 46 In umbilical cord derived hMSCs, loss of CD105 expression has been linked to decreased ability to inhibit Th1 lymphocyte proliferation in co‐culture.47 Decreased hMSC secretory potency and chemokine receptor expression can reduce homing ability to injured tissues.48 The results of this study indicate that loss of properties is also linked.
