MSCs stimulate heme oxygenase 1 and the downstream ferritin heavy-chain subunit in cytokinic stress conditions. a, c Transcripts were measured by RT-PCR and values were normalized on HPRT. b, d Blot signals were normalized with Ponceau S staining of the whole lane. Data are representative of six independent experiments for RT-PCR analysis and eight for western blot analysis and are represented as median ± interquartile (ANOVA; *p < 0.05 vs. respective controls and #p < 0.05 vs. stressed islets alone)
