Fig. 7. Impact of HSA-heme on the differentiation of monocytes into DCs.

a Phenotype of DCs generated in the presence of HSA-heme. Monocytes were differentiated into DCs in presence of 10% FCS, 1% HSA or 1% HSA-heme and analyzed after 7 days for expression of typical cell surface markers (filled histograms) compared to the isotype control (dotted histograms) via flow cytometry. Data shown are representative of four independent experiments with four different donors. b HSA-heme modulates cytokine production of DC upon stimulation with LPS (mature DCs). Supernatants were collected from DCs and mature DCs and analyzed on day 7 (n = 3). Means ± SEM are shown. *P < 0.05 (one-way ANOVA followed by Tukey’s multiple comparison test).
