Fig. 6. BMP4 and PGE2 decreased in SS patient’s BMMSCs.
a BMP4 mRNA expression in BMMSCs from patients with primary Sjögren’s syndrome (pSS) and healthy volunteers. b Western blot of BMP4 expression in BMMSCs from pSS and healthy volunteers. c PGE2 levels in supernatant of BMMSCs from healthy volunteers and SS patients (n = 5, three independent experiments). Values are means ± SD. Student’s t tests and one-way ANOVA. *P ≤ 0.05; **P ≤ 0.01.
