IL-1β Stimulated Human Umbilical Cord Mesenchymal Stem Cells Ameliorate Rheumatoid Arthritis via Inducing Apoptosis of Fibroblast-Like Synoviocytes

TRAIL receptor-Death receptor 4 (DR4), DR5, and lymphocyte function-associated antigen 1 ligand-intercellular adhesion molecule-1 were upregulated in IL-1β-stimulated human fibroblast-like synoviocytes-rheumatoid arthritis.
