Fig. 3From: Hypoxia-induced the upregulation of stromal cell-derived factor 1 in fibroblast-like synoviocytes contributes to migration of monocytes into synovium tissue in rheumatoid arthritisHypoxia induced SDF-1 expression in fibroblast-like synoviocytes. a RT-PCR was performed to detect SDF-1 level in fibroblast-like synoviocytes under hypoxia stimulation. ***P < 0.001. b Western blot was performed to detect SDF-1 level in fibroblast-like synoviocytes under hypoxia stimulation. c ELISA was performed to detect SDF-1 level in fibroblast-like synoviocytes under hypoxia stimulation. ***P < 0.001. d SDF-1 level was investigated in RA synovial tissue by immunofluorescenceBack to article page
